A classic car high voltage wire is no different from a regular copper single core cable, except powerful protection from high voltage radiation. The insulating layer is made from different materials. With the development of technology, manufacturers are increasingly focusing on a powerful and elastic material - silicone.

Until the 30s of the last century, the influence of impulse noise on car instruments was neglected. The resistance of the copper core was close to zero. With the advent of car radios, it turned out that pickups from high-voltage electrical cords create radio interference so strong that the devices crackle and cannot be sources of pleasant sound. Engineers came up with the idea of ​​installing in series with a current-carrying core, a 4-15 kOhm resistor. This reduced radio interference.

Modern high-voltage wires are made with a conductive layer of graphite with a resistance of 5-20 kOhm. They can be used without an additional current limiter.

Twisted steel wires are also used, reinforced with strong Kevlar threads, with a ferrimagnetic core.

Materials used as insulators:

• polyethylene;
• polyvinyl chloride;
• feroplast;
• silicone;
• metal winding, like a screen.

Insulation is a combination of layers, characterized by the presence of one or the other component, depending on the preferences of the manufacturer.

Symptoms and malfunctions of high voltage cables

Among the main symptoms:

• engine troit;
• traction changes unreasonably sharply;
• the engine stalls, it starts poorly;
• increased fuel consumption;
• increased CO emissions;
• BB wires spark;
• engine power has decreased.

Symptoms show that the malfunction is caused by incomplete combustion of fuel and is associated with the ignition system, although similar signs of breakdowns are also characteristic of other auto systems.

Diagnostics of high-voltage wires

If you find the above malfunctions in the car, then pay attention to the high-voltage ignition wires. In modern cars, they work for a long time, more than 100 thousand km. But in cars that have traveled only a thousand kilometers, but have stood in the garage without moving for more than five years, there are the same problems. Microcracks appear in the insulation, and the cable breaks through with high voltage to the case.

Find a dark place, preferably in the garage, clean the wires from burning and grease. Start the engine and see what's going on under the hood. You will see a slight glow around the armored wires. If you do not see, and the engine is running, then this is very good. But if the glow is pronounced or the wires sparkle, then these are signs of a violation of the dielectric.

Sometimes grease or oils that get into the tips are to blame for leaks. In this case, the voltage becomes an extremely dangerous source of ignition of the car.

It is easy to diagnose the ignition system by the sound of the audio system. The method is only suitable for car owners with old analog radios. As soon as problems with cables begin, the radios crackle in sound and no power filters will help.

How to check armored wires? You can determine which one is faulty using a conventional analog or digital tester. Checking high-voltage wires does not require the qualification of an electrician, it is enough to be able to use a multimeter and remember that no matter what product you use, the grease on the insulation must be thoroughly cleaned.

Types of conductive cores of high-voltage cables:

• copper;
• copper with built-in resistor;
• graphite;
• twisted steel winding on the dielectric.

In the first case, the resistance of high-voltage wires will approach zero, in the next three, it should range from 4 to 20 kOhm, depending on the brand. If the multimeter displays a higher reading, then this is a sign of unsuitable cord. Grease, on an uncleaned probe and a dirty surface of the insulation will distort the readings of the device. Grease can be conductive and by measuring the resistance of the strand, you can actually see the result of the resistance of the grease and not the wire.

Checking with a tester will not be able to detect dielectric failures and contact problems in the clamps if they are covered with grease.

How to check high voltage wires without a multimeter? Just bring them with the bare end to the body of the car. The presence of a spark indicates the health of the circuit. The spark must be powerful and stable.

During measurements, be sure to bend the braid and insulation, especially at the points where the connectors are attached. If the readings of the device change, then the device is unreliable, and it is better to replace it.

How to make and replace a BB cable yourself

For example, you have determined that the armored cord of the fourth cylinder penetrates the body or is completely broken and does not affect the spark plug. Replacement required.

Replacement of high voltage wires simple operation which can be performed by any motorist.

It's safer to buy the complete set. Practice has shown that products of the same manufacturer produced at the same time fail almost simultaneously.

If this is an expensive solution for you, then you can make armored wires yourself. It will be much cheaper. Before you make them with your own hands, decide that the connection diagram is clear to you.

To make a kit with your own hands, it is enough to purchase:

• silicone vacuum hose with a diameter of 7-8 mm;
• tips, old ones can be used if they are in good condition;
• copper stranded cord with any suitable section;
• half-watt resistors with a nominal value of 1-1.5 kOhm.

The additional element required to smooth out radio interference in modern cars should be in the range of 10-20 kOhm. If you install one element of this rating, then there is a high probability of its failure during peak loads. It is better to distribute the load on several series-connected devices with a nominal value of 1 kOhm.

We insert a chain of resistors soldered with our own hands into a silicone hose, cut it off and clean it. Then crimp the ends. To improve contact, graphite grease is used at the joints.

If the insulators are difficult to put on, lubricating them with soapy water helps.

Disadvantages of the method:

• there is a high probability of breaking the soldering of contacts, in conditions of high temperature;
• dependence of the ruler on one part;
• the difficulty of determining the failed element.

If you decide to make cables with your own hands, then do not forget that high-voltage wires of zero resistance are connected only through series resistance.

High-voltage wires, the order of their connection

If the distributor cover is installed correctly with your own hands, then the connection diagram for high-voltage wires will be as follows:

• distributor output looking to the side front bumper, to the first cylinder;
• tip looking down to the third cylinder;
• looking back to the fourth cylinder;
• looking up to the second cylinder;
• the central current carrier always goes to the ignition coil

Do not forget that the order of connecting high-voltage wires in cars is such that their length will not allow you to make an incorrect connection. Therefore, when making cords with your own hands, try to follow the same principle so as not to get confused.

Zero resistance high voltage wires are the best wires for almost any car. In this article, you will learn how to make wires using high-voltage from gas trucks and wires from the ZIL-130 car, as well as with a wire PMWC.

Making high-voltage wires with your own hands is not only easy, but also cheaper than buying original ones, and the quality will be better! I will tell you how to make wires with your own hands. The instruction is universal, such high-voltage wires are suitable for VAZ, Audi, or even Hyundai and Kia.

Why do I need high voltage resistance wires?

Each car has high-voltage wires, their task is to pass a lot of volts through themselves - up to 20,000 volts!

If we take that wire cc is a freeway, then volt is a car. There are obstacles in the wires - resistance, and the fewer obstacles on the freeway, the faster and more often they get to the place - the spark plugs.

Now they make wires of poor quality - without copper at all, thin as a hair, hence there are few such wires. The operation of the engine deteriorates, up to tripling or it will not be possible to start it at all. Therefore, wires of zero resistance will come to the rescue, thanks to them improve engine performance, there will be traction at the bottom, as well as fuel consumption will decrease. It doesn’t matter if the injector or carburetor is high-voltage wires of zero resistance, they are often better than original or factory ones.

To check the resistance, just for this, take the simplest multimeter and attach the probe to the ends, the screen will show the real resistance of the wire. Ideal for most cars resistance more than 3 kOhm is not normal. Therefore, we begin the work of manufacturing high-voltage wires.

Do-it-yourself high-voltage wires of zero resistance from PMVC

What are PMVC wires- these high-voltage wires work with low voltage (just for cars), but they are also used for neon signs and other low-current systems. Such wires are not sold in every store, but the cost will please you - about 10 rubles a meter. The resistance of the PMVC wire is zero. Making high-voltage wires from PMVC (not to be confused with PVMK!) is quite simple.

Necessary materials: old wires for your car, a PMVC cable with a cross section of 0.75 mm square, and with a voltage of up to 20 kV, the wire will be marked PMVC 0.75-20.

First, remove the metal lugs and caps from the old high voltage wires. You can use WD-40 or other silicone lubricant to remove the rubber caps. Next, cut the desired length from your PMVC wire and strip the insulation.

Next, crimp the tips and new wires and insert the rubber caps. High voltage wires are ready! Just in case, if you doubt the quality of your work, then carry a set of working high-voltage wires.

Do-it-yourself high-voltage wires of zero resistance from GAZ, ZIL

For gas and zil-130 there are wires with zero resistance, the procedure is the same as with the previous option. You will need new BB wires from gas or zil-130. In a store, such wires are easier to find than a mpvc cable, so this is also a good option.

It should be borne in mind that there may be thin wires with resistance on the ZIL-130, you do not need to take such wires. It is worth buying wires with rubber insulation and copper multilayer core.

Undoubtedly, the advantage of making wires from gas-zil is that it is easier to buy them, but the price for the set will be a little higher - 200-400 rubles. The resistance on them is also zero, but there is a minus. In winter, gas and Zilovsky wires are tanned due to rubber insulation, so because of this, the mileage will be less than the high-voltage cable pmvk.

They write that the mileage of home-made high-voltage wires is about 100 thousand kilometers, although the original wires have greater resistance and less mileage of no more than 60 thousand, usually 30-40 thousand km.

Appointment of high-voltage wires, general information. The main task of high-voltage wires is to transmit electrical impulses from the ignition coil to the spark plugs. Therefore, they must:

• withstand high voltage (up to 40,000 V), transmit pulses with little loss,
• provide a minimum of interference to radio-electronic equipment,
• have good insulation to prevent current leakage,
• retain its properties in a wide temperature range - from minus 30°C in winter to plus 100°C or more when the engine is running in summer.

To transmit a high-voltage pulse with minimal losses, it is desirable to reduce the electrical resistance of the wire. Therefore, many years ago, wires with a copper conductive core were successfully used. But with the beginning of the widespread use of electronic devices (radios, televisions, electronic on-board systems in the car itself, etc.), their main drawback began to appear - the emission of a large amount of electromagnetic interference.

To reduce them in the high-voltage circuit of the ignition system, additional electrical resistance is used.

An interference suppression resistor can be built into the distributor rotor (runner), spark plug or its cap in various combinations. In addition, the carbon electrode in the distributor cap has resistance.

At present, the most effective and most common way to reduce interference is to use high-voltage wires with distributed resistance. Construction of high-voltage ignition wires Modern wires consist of a conductive core, insulation (protective layer), metal contacts and caps (Fig. 1).

The conductive core (Fig. 2) is of several types:

• stranded copper with a resistance of 0.02 Ohm / m (Ohm per meter of wire length). With such wires, additional noise suppression resistors are needed;
• non-metallic with a metal "wrapping" - distributed resistance up to 2 kOhm / m. The central part of the core is made of fiberglass impregnated with graphite, linen thread or Kevlar3. It is often covered with a layer of ferroplast4, which, due to its properties, also prevents the propagation of interference. A thin metal wire is wound on top. As a rule, additional noise suppression resistors are required;
• non-metallic with high distributed resistance. Wires with such a core are installed without resistors.

A core of this type can be made of various materials, for example, options are often found from:

• cotton yarn impregnated with a soot solution. Sometimes it is reinforced from above with a cotton or nylon braid. Resistance 15-40 kOhm/m;
• polymer "vein" with a resistance of 12-15 kOhm / m. A reinforcing thread may be omitted inside it;
• fiberglass strands with graphite sprinkling.

Insulation - a single-layer or multilayer protective dielectric coating of a conductive core (Fig. 3). Intended for:

• leak prevention electric current;
• protection of the core from moisture, fuels and lubricants, harmful vapors and high temperatures in the engine compartment, as well as mechanical damage.

It is made of various types of plastics (for example, PVC), silicone, rubber in various combinations. Sometimes the mechanical strength of the insulation is increased by fabric, cotton, nylon, fiberglass or polymer braid.

Metal contacts (lugs) provide electrical connection of the conductive wire with the corresponding contacts (sockets, high-voltage terminals) of the spark plug and ignition coil or distributor cap. Primary requirements:

• reliable contact with conductive wire. Achieved by crimping or soldering (with a copper core);
• strength of the wire. It is achieved by tight crimping and sometimes additionally with "teeth" and a special bulge (Fig. 4);
• reliable connection with the terminals of the spark plug and ignition coil or distributor cap. To do this, the wire contact may have a protrusion, petal or special spring;
• sufficient corrosion resistance to maintain reliable contact during operation. Achieved by the use of non-ferrous metals or a coating that protects against external influences.

The contacts to which the high-voltage wire is connected are of several types. The most commonly used are shown in Fig. 5, and at different ends of the wire they may differ.

The caps protect the connection points of the wire contacts with the corresponding terminals of the coil, distributor and spark plugs from aggressive environmental influences and prevent leakage of electric current. Basic requirements for them:

• the tightest connection with the details of the ignition system so that dust and moisture do not penetrate the contacts. Sometimes, after prolonged use, it is possible to remove the caps only with the help of a special tool;
• resistance to high and low temperatures, as well as to their sharp drop.

Caps have a different shape, are made of rubber, silicone, plastic or ebonite. Some of them have an additional noise suppression resistor built in (Fig. 6) or a metal shield to reduce interference. Malfunctions of high-voltage ignition wires The main wire malfunctions are a break in the electrical circuit and current leakage.

A break in the electrical circuit occurs most often at the junction of the metal contact of the wire with the conductive core and other parts of the ignition system, for example, when:

• removing the wire;
• poor connection with the conclusions of the corresponding elements of the ignition system;
• oxidation or destruction of the core.

In places where the connection is broken, sparking and heating occur, which further worsens the situation and can lead to burnout of metal contacts or wires.

Electricity leakage occurs through contaminated wires, candles, a distributor cap and an ignition coil, as well as if the insulation and caps of the wire are damaged, so their dielectric properties deteriorate during operation.

At low temperatures, high-voltage wires become more rigid, and the likelihood of damage to their insulation and caps increases. In addition, due to the constant vibration that accompanies the operation of the engine, the joints are loosened, which can lead to poor contact, for example, in the distributor cap. Spark plug caps suffer the most from elevated temperatures, since they are closest to the heated engine parts and, moreover, often fail when removed.

Over time, all elements of the ignition system are inevitably covered with a layer of dust and dirt, moisture and vapors of fuels and lubricants, which are current conductors and significantly increase leakage, especially in wet weather and if the insulation is damaged. In addition, microcracks increase further from moisture and dirt. Recommendations for choosing high-voltage ignition wires VAZPri selection of high voltage wires it is advisable to focus on the recommendations of both their manufacturers and engine manufacturers.

When buying, it is useful to carefully study the packaging. It is desirable that the models of cars or engines for installation on which these wires are intended be indicated on it in Russian. The absence of an indication of the manufacturer of the wires and its "coordinates" is a sufficient condition for refusing to purchase. Also, you should not buy wires with spelling errors on the packaging, most often in the word silicon. It should be borne in mind that there is only the international standard ISO 3808 for high-voltage automotive wires, and there are no domestic ones, so the manufacturer himself determines the presence and content of the inscriptions on them.

If the ignition system gives a high-voltage pulse with low energy, for example, in cars with a contact ignition system (most rear-wheel drive VAZs), then you should not install wires with a high distributed resistance. This will reduce the power of the spark and, under adverse conditions, misfiring of the combustible mixture is possible (for example, when starting a cold engine in winter).

Wire resistance can be measured with a tester. However, for wires with a winding of a conductive core, this method is not correct, since when working on an engine, the value of their resistance changes. This is due to their design features.

The level of interference created by both the electrical equipment of the car as a whole and high-voltage wires can be assessed using the receiver (car radio) installed in it. The order of work for such a check is given in the diagram.

When choosing wires according to the insulation material, the voltage in the ignition system of a particular car should be taken into account. At its maximum values, which may be indicated in the repair manual, the insulation must not allow breakdown. Preferably wires with insulation and caps, the material of which does not become hard and brittle in the cold and withstands high temperatures in the engine compartment, such as silicone. In addition, it is less wetted by water, which means that the probability of electrical breakdown is reduced. The silicone feels waxy to the touch, and the wires made from it allow severe kinks.

During the operation of the car, first of all, it is necessary to keep the wires clean and dry. To do this, you can, for example, periodically wipe the distributor cap, ignition coils, spark plug insulators and the wires with caps removed from the car with gasoline.

It is often possible to determine insulation breakdown during engine operation by ear (clicks are heard) or visually. If you open the engine compartment at night, then the place of the current leakage will be visible from the spark. In the dark, a glow (shine) is sometimes noticeable around the devices of the ignition system due to humidity and air ionization, for example, before a thunderstorm, or with large current leaks.

A wire break in the winding of a non-metallic conductive core (Fig. 2, b) may not appear at idle speeds of the crankshaft and at low loads, while at high loads, the engine will “triple” if the wire leading to the candle is damaged or stall, if the central one is faulty.

Good contact in the tips prevents the loss of impulse energy transmitted to the candles. Therefore, it is advisable to periodically check whether the tips are well inserted into the sockets of the corresponding elements of the ignition system.

To prevent damage to the wire, it is recommended to remove it, starting with the cap, and not pulling out the insulation.

The tightness of the caps at the junctions of the wires reduces the oxidation of the tips and the subsequent deterioration of the contact. Therefore, it is important to put on the caps to the end, and if cracks appear on them, replace them.

Interference is generated due to voltage pulses of high frequency in the ignition system. For domestic cars their values ​​are as follows: rotor - up to 8 kOhm, candle - 4-10 kOhm, candle cap - 4-13 kOhm, central electrode - 8-14 kOhm. Flexible artificial material with high strength. 20% polyvinylchloride compound PDF and 80% ferrite or manganese-nickel and nickel-zinc powder. You can compare the energy of a spark with one or another wire by connecting an arrester instead of candles on a car and turning the engine crankshaft with a starter. In this case, it is desirable, and on vehicles with a catalytic converter of exhaust gases, it is necessary to turn off the fuel supply. A large total resistance in the secondary circuit will make the spark paler and thinner. The arrester consists of two electrodes in an insulating housing, the distance between the ends of which is 7 mm. You can imitate the arrester by securely fastening the tip of the high-voltage wire at this distance from the metal part of the engine.

To high voltage wires many motorists are treated as a minor detail, and in specialized publications little attention is paid to them. And most sellers in retail outlets can’t say anything sensible, they advise what to buy, based on personal sympathies, and their own benefit. And that's the thing - wires are thrown between the ignition coil and candles, the current is carried out. Wires, they are wires to conduct current. What can be a significant difference between them that affects the operation of the car? But not everything is so simple. Conduct and protect.

The main purpose of high voltage wires is the reliable transmission of high voltage electrical impulses from the ignition coil to the spark plugs. Depending on the ignition system, the generated voltage can range from 25 kV to 50 kV. And, it would seem, the lower the electrical resistance, the less energy loss, the better the ignition system will work. However, there is a downside to electrical resistance close to zero - high level electromagnetic interference, which has a devastating effect on the work of a modern car stuffed with electronics. Therefore, the motto of high-quality high-voltage wires sounds almost like the American police: "Conduct and protect." Protection functions are reduced not only to interference suppression, but also to the prevention of other adverse phenomena.

Firstly, the wires themselves must be resistant to the aggressive environment under the hood of the car, withstand various temperature conditions (from -60 ° C to +240 ° C) and not lose their conductive qualities.

Secondly, the seemingly simple design of high-voltage wires should prevent current leakage up to contact with the tips of the candles. Poor-quality or faulty wires can disable some car devices, such as an electronic system, as well as complicate the operation of the engine with other troubles. Current leakage or increased resistance leads to a decrease in the strength of the impulse and, as a result, either to slow ignition, or to “triple” and “fade” of the engine at high speeds, or to no spark at all, especially if the candles are even slightly dirty.

As a result, dynamics decreases, fuel consumption increases (by 4-7%) and exhaust toxicity. Price or resource? High-voltage wires consist of a conductive core, insulation (protective layer), metal contacts and caps. Optional element are combs that collect wires into a bundle. If subdivided according to the materials used and production technology, then all high-voltage wires can be conditionally classified into three categories.

The second is solid wires with PVC or EPDM (a type of polyurethane) insulation. Such products require additional noise suppression resistors, in addition, PVC insulation over time, under the influence of gasoline vapors, frost and high temperature, becomes covered with microcracks, water penetrates into the wires, the resistance decreases sharply and current leakage occurs. It is with these wires that most domestic-made cars were equipped and are being equipped. Wires are recognized as the most technologically advanced today, where a conductive core made of non-metallic material is used as a core, be it fiberglass, polymers, graphite, flax, cotton, Kevlar, as well as their combinations. And silicone insulation (in extreme cases, silicone rubber) provides high breakdown voltage and no losses in the ignition system, which increases the overall power of the spark, more complete combustion of fuel, increased engine power and optimal gas mileage.

For example, silicone wires manufactured by the Citron concern (Stavropol Territory) can last at least 160,000 thousand kilometers without limiting their service life. At the same time, non-silicone - 30.000-50.000 kilometers or 2-3 years of operation in harsh Russian conditions. At the same time, more technologically advanced silicone wires cost 3-4 times more than their counterparts. So the choice of today's buyer is between price and resource.

The high-voltage wires of tomorrow are distinguished by the latest materials that increase resistance to aggressive environments, have better insulating and environmental characteristics. For example, the American corporation Delphi Packard Electric Systems offers the global automotive industry a cable based on PPO technology, which is more durable and friction resistance is 4 times higher compared to analogues. And at the same time allows to reduce the weight of the product by 25%. Since 2007, it is planned to equip Mercedes C-class with wires from this cable. It is worth noting that it is Delphi Packard that is the world leader in the production of cable products from silicone. The high-voltage wires of most American cars are made from its materials. The Citron concern was one of the first in Russia to use Delphi Packard materials in the production of wires and secured a worthy place in the market. First, you should pay attention to the information indicated both on the packaging and on the wires themselves: manufacturer, applicability, etc. Very often, "left" manufacturers make mistakes in writing the word "silicone" in English. The correct option is "silicone". This is such a common mistake that even one of the most famous Russian auto publications in a large material indicated “silicon”, which in Russian means “silicon”. Secondly, pay attention to the wire caps. They must ensure the tightness of the connection and protect the contact tips. High-quality caps are made of rubber based on silicone rubber. The wall thickness must be at least 3 mm. It is at the junctions of contact with the conductive core and other parts of the ignition system that the electrical network is most often disturbed. This happens, as a rule, either when the wires are removed (often they pull directly on the wires) or a poor connection to the terminals of the corresponding elements of the ignition system due to oxidation, loose fit, etc. Thirdly, you should pay attention to the quality of the high-voltage wire cable itself. The best ones are made of silicone, you can check their reliability simple ways. Bring the cable into an open flame - high-quality insulation should not easily melt or ignite. Twist the cable tightly. Signs of displacement, sliding between the sheath and core, as well as a crunch indicate a poor quality of mechanical adhesion between the sheath and the insulator. Also try to move the insulation layer longitudinally. The cable must be practically a monolith, otherwise, when installing and removing the wire, protection may be violated.

This material will be devoted to such an interesting and controversial topic for more than half of the world's population as high-voltage wires of zero resistance for car ignition systems.

Much of this issue is shrouded in darkness, but more and more often this topic is raised on forums, authoritative and not very sites, and in some other sources for providing bottomless information, but without any specifics.

Most often, these discussions develop into a pro and con argument, then a very smart person appears (from his point of view) and sends everyone to read a 7th grade physics textbook. Moreover, without specifying the page and paragraph, where, in his opinion, everyone should know the truth and stop talking nonsense about wires of zero resistance.

And if you do not heed his advice, then your car will certainly burn down the day after tomorrow or something bad will happen to it, but no one knows what. But you still need to be afraid of who knows what and who knows when.

In general, this is where the discussion ends, as always - whoever had doubts got scared and went to other forums to tell horror stories about BB wires of zero resistance, and those who installed them continued to operate their car, ignoring the terrible information in the physics textbook for 7th grade.

This article will focus solely on my opinion and the opinion of my friends and community members, whom I respect and listen to their experience, as they to mine. It is to experience, and not to the knowledge of buzzwords and all the pages of a physics textbook for grade 7.

This topic has bothered me for a long time. I don’t remember what year it was, but I came across an article from the magazine “Behind the Rulem”, where they empirically found out that BB wires of lower resistance are doing a little better than those with higher resistance. That is, the quality of combustion was maximum when using wires of lower resistance.

Zero resistance wires pros and cons

It’s worth mentioning right away that there are no wires of zero resistance. Sometimes low, tending to zero. But we will call them - wires of zero resistance. It's just easier and fewer letters.

Let's say that the wires, which will be discussed further, have a resistance of 13 Ohm / km.

First, let's look at a few terrible arguments against zero-resistance wires. A kind of rating of horror stories. We will not consider the active and inductive resistance of wires, but we will leave it for schoolchildren of the 7th grade.

Scarecrow #1 - if the spark plug electrodes are short-circuited, the coil will fail if the wire has zero resistance.

Firstly, the ignition coil is more afraid of an open in the high-voltage circuit than a short circuit. That is why it is strictly forbidden to disconnect the BB wire while the engine is running to check the spark or, for example, when measuring compression. In this case, it is necessary either to turn off the coil completely and in a low circuit, or use a spark gap

Secondly, there will be no short circuit even if the electrodes of the candle are taken and closed. Each candle already has a built-in resistance of about 5 kOhm

And if you read a physics textbook for grade 7, then you should know that a resistor can only have a malfunction in one direction, i.e. it can only increase its resistance, it cannot decrease it. So the short circuit does not smell there.

Scarecrow #2 - wires with zero resistance can only be put on the old contact ignition, otherwise there will be interference

And it seems to me that the opposite is true. Interference for the most part appears just in the contact ignition system due to the presence of these contacts themselves. Especially in the distributor.

Practice has shown that there are no visible and audible interference when installing wires of zero resistance. At least on the Chevrolet Lacetti.

Horror story No. 3 - wires with zero resistance can only be put on the old contact ignition, since the voltage in the secondary circuit is lower there

The declared operating voltage of the PMVC wire, with a nominal outer diameter of 6.8 mm and almost zero resistance, is 25 kV. Not maximum, but working!

Scarecrow #4 - everything will burn to hell when you install wires of zero resistance. And the ECU too.

This is the most terrible development described in a spiritual book called "Physics for the Seventh Grade". The legends in it terrify and damage everyone who wants to put wires of zero resistance.

Of course, the ECU can someday burn out. For whatever reason. But it's unlikely to be wires.

It is also worth noting that the secondary circuit of the ignition coil does not have a direct electrical connection with the primary circuit.

Scarecrow #5 - Why don't manufacturers make wires like this? Because it's terribly dangerous!

Why don't they do it? I sometimes came across these. For example, Pro.Sport. They have resistance not in kiloohms, but in ohms.

Well, most manufacturers do not need it. The conveyor rivets, sales go, profit drips. What else is needed? Everyone cuts off their part of the pie from one bay of cheap wire, with no one knows what kind of residential wire, and does not blow into the mustache.

Yes, and it's cheaper. Can you imagine how much more expensive it will be to make wires with a copper core? And for a year? And for two? These are kilometers of wire and tons of copper.

Yes, and introducing new technologies is an extra cost and once again strain the brain. Vaughn, NGK and Bosch still cannot clearly explain the reason for the appearance of a yellow rim on the candle insulators.

Scarecrow #6 - in "Murzilki" it is written that BB wires should be 3 kOhm

In all the Murzilki that I saw, it was clearly written that the candle wires should be NO MORE THAN 3 kOhm. About NOT LESS nothing is indicated anywhere. I think the point is clear.

Now let's talk about the advantages of high-voltage wires of zero resistance.

These wires are already in many and I heard only positive feedback. This article will also use reviews, opinions and photos courtesy of our community members.

I would like to express my special thanks to a member of our community for their dedication, support and provided material.

I will not paint for a long time and a lot of all the advantages and positive points after installing wires of zero resistance, but I will note the main ones:

How to make wires of zero resistance with your own hands? Very simple. The whole process can be divided into 4 stages:

• purchase of two meters of PMVC wire
• cut up old wires and donate them for new ones
• connect new wires with lugs from old wires
• experience positive or negative emotions after installation and report it to the whole world.

Now let's briefly go over each point separately.

Where to buy wires of zero resistance

PMVC is a high-voltage mounting wire with a multi-wire copper core (TPZh) with organosilicon insulation "SILICON", flame retardant.

High-voltage silicone wire PMVC, used:

• in high-voltage installations of low power, for the installation of electrical equipment
• for installation of outdoor illuminated advertising with neon components. It is used for connecting (mounting) elements of gas-light lamps, both among themselves and with their power source of various types (electromagnetic or electronic);
• for the manufacture of high-voltage ignition wires with low resistance (the resistance of the 1.5-25 kV PMVCL wire is 13.7 Ohm / km).

Now it is no longer difficult to buy it on the Internet. For example, in Ukraine there are several stores selling this product with a price of 30-40 UAH/m.

There are also different colors and the possibility of purchasing even tips, so as not to waste time cutting old wires.

Here we have purchased black wires with tinned copper for the next set of BB wires

An example selection table looks like this:

Nominal section, mm 2	Operating voltage, kV	Nominal radial insulation thickness, mm	Nominal outer wire diameter, mm	Price rub/meter including VAT*

You need to purchase 2 meters of wire for one car.

We first pay attention to the diameter of the old wires, which is 7 mm

First we need to disassemble the old wires. This is necessary in order to connect the lugs from the old wires to the new wires.

To do this, we insert a small screwdriver between the wire and the tip in order to glue the wire and the insulator of the tip together, otherwise they stick well to each other over time

Use a knob or screwdriver to push the tip out of the insulator

This is how the metal tip comes out of the insulator

And he's already out

Now, in the same way, glue the small insulator and wire with a screwdriver

We take out the wire together with the tip from the insulator

We pull out the wire, and on the other hand we push the tip. Everything comes out without problems.

It turns out this is such an uncomplicated picture

Now it remains to pull the insulators onto the new wire, crimp it into lugs and pull the insulators onto these same metal lugs /

We remove the old wire from the small tip

Crimping a new high voltage wire

Now we put an insulator on the wire

If it is very tight, then you can use the auxiliary wire

Now we crimp the tip and pull the insulator over it

It turns out such wires of zero resistance in black, which you can’t immediately distinguish from ordinary ones

Or like this - white

To make it easier to disassemble / assemble, you can lubricate the whole thing with grease to protect electrical contacts. This will make our work easier and protect contacts for a longer period, since everyone knows that copper loves to oxidize. By the way, wires with tinned copper are now on sale. I think that the acquisition of such wires will be a little more practical.

Well, if there is no such spray, then you can use something at hand - WD-40, Silicone Grease etc.

The finished result looks like this

And of course the wires at your workplace

Here is the result.

In the end, of course, it is worth paying attention to the fact that we are all adults and must make our own decisions. This also applies to high-voltage wires of zero resistance. To follow these recommendations or not is everyone's business.

The purpose of this article is not to give endless pros and cons, which are a dime a dozen on the Internet, but to show in practice that everything works. It just works, no ifs and no ifs.

And not only that no negative consequences were noticed during the operation, but there were also many positive moments that were not even counted on.

At least on the Chevrolet Lacetti, none of my acquaintances and friends for a minute doubted the correctness of their choice.

It is worth noting that these wires were installed on engines with a mileage of under 200 thousand km. and one with a mileage of 250 thousand km. Both in Russia and in Ukraine.

In general, everyone has their own thought on their shoulders, so decide for yourself whether it's worth it or not.

If possible, I will supplement the article with new facts.

Also interesting is the opinion of people who have tried these wires on their car. We will be glad if you state it in the comments.

All of the above is solely my personal opinion and the opinion of people I respect.

Peace and smooth roads to all!

P.S. So I flew almost 1000 km on wires of zero resistance. As promised, I will supplement the article with new facts and sensations.

For the sake of experiment, I put old wires with resistance. Subjectively, the difference is barely noticeable and is as follows:

• on wires of zero resistance, the consumption is really a little lower, but the machine has become sharper and very sensitive to the gas pedal.
• On wires with resistance, the consumption is correspondingly higher. But the car drives more smoothly, which is more to my liking.

These are purely my observations and subjective opinions. Others feel a little different, which suggests an individual approach to each car. Perhaps the mileage, the fuel used, the technical condition of the car, the driving style, or something else.

In general, the goal of the experiment and writing the article was achieved - BB wires of zero resistance work, they do not cause problems and malfunctions. Save fuel. And feelings ... Feelings are such a thing that you can’t please everyone

So don't expect zero resistance wires to meet all your needs. Or maybe satisfy...

Therefore, as before, I will say - decide for yourself whether it is worth it or not.

If it weren’t for the goal of conducting an experiment, writing an article, expressing my opinion and feelings, helping others to decide, then I probably wouldn’t bother with wires of zero resistance. As my practice has shown personally, out of all this fuss, plus only a slight decrease in fuel consumption. I didn't see any other real benefits.

Others, of course, have different opinions. It is interesting to learn about them in the comments. The only thing is, please write about real experience, and not about guesses and knowledge of a 7th grade physics textbook
