Very much in cars is under the control of the efficiently organized system of "running electrons", so the foundations of the automotive electrician must be known to each driver so that no malfunction could find it surprise. About this further in the article.

Modern electronics of the car to help the driver, which is an electronic filling of a modern car

Modern cars are characterized by quite complex electronics that facilitates the driving process that reduces the likelihood of an accident and keeping the driver and passengers in the car's cabin as comfortable as possible. But, the initial purpose of any auto electrician is the launch of the motor and its subsequent maintenance in a working condition, otherwise the car will not be able to move off and perform its main function. This system includes batteries and electric generators that are power sources of any car.

This also can be attributed to the mechanisms that are responsible for the initial start of the vehicle and its further movement. This control unit (mechanical or electronic), spark distributor-lock braking system, a starter, candles, High coil.

The secondary elements electricians are sources of illumination - lights, turn signals, brake lights, marker lights, all kinds of lights. In addition, it is noteworthy and an audio signal that plays a major role security, and various sensors that monitor operation of the vehicle, and other various elements.

Problems electricians, the most common problems, how to solve them:

Car electronics, one might say, deservedly occupies a leading position in the vehicle, as this category include a lot of structural components, so a fault in the system are fairly common. Often they are the result of poor-quality contacts, in addition, bundles are experiencing wear and tear, which is why fray. Quite often there are defects in the sensors, which entails their malfunction.

Moisture, dirt and dust has a negative effect on the bulbs, the electrical circuit and mounting blocks. It is important to monitor the status of the sensors, especially those that are responsible for the correct operation of the engine.

After all, if they do not testify either of these readings will be incorrect, and the correct engine work will be in doubt, but it would entail its rapid failure. It is important to regularly undergo diagnostic control unit at the station, because the "smarter" this mechanism, the less the driver can help him in case of breakage.

if bad contact in the electrical

Poor contact is a fairly common fault of the car wiring. It can be detected with a voltmeter. There are two verification method. When using the first method, it is necessary to connect one lead of the voltmeter to the mass, and other touch pin connections on both sides, measuring the voltage. When this voltage drop should not be more than 0.5 V. When using the second method, a wire must be attached to terminal connector at one end and the other - to the terminal on the other side of the connector. If the voltmeter reading will be more than 0.5 V, the connector is necessary to clean contacts.

When repairing electrical wiring, it should be taken into account that in modern cars, single conducting electrical wiring is becoming increasingly relative. Negative wires are connected together and attach to the body. In case the mounting will weaken and the contact is lost, it means the path that passes current can pass through other users who will work without their activation. The most common such malfunction is to light on the rear lights of several lamps when the contact is lost in the negative wire and the car body.

wire wear

Do not forget that the harnesses of the wires are subjected to natural wear, i.e., systematically shakes, which requires either their complete replacement, or at least an additional winding with an insulating tape.

fault sensors

To the motor does not fail, the driver must ensure the correct operation of its sensors. More precisely, the designers must provide it, but it is precisely how the motorist will exploit the vehicle will depend on their performance.

the consequences of the negative impact of the atmosphere

All, light bulbs, mounting blocks and electrical circuits can work several times longer, if they do not affect the influence of moisture, dirt and dust. However, not rarely malfunction entails the negligence of the collectors leaving "unborn" in contacts. As a result, the system will start working with interruptions, after which it can overdo it. Then you have to change not only contact, but all its elements.

bad contact at the battery

With the oxidation of the terminals of the battery, probably had to meet a single experienced motorist. Such a terminal is essentially covered by a raid, which prevents the correct operation of the rechargeable battery. As a result, with time the vehicle and can stop running. This is especially true in winter. In some cases, oxidation is so intense that the flare is covered with the terminal completely. To correct the situation, it is enough to clean the contacts. However, the elimination of the consequences will not fully solve the problem - it is necessary to find the cause of this phenomenon.

The most valuable tips on the auto electrician

Fundamentals of automotive electrics for beginners and not very complicated. If you know them and follow them, you can not only detect simple malfunctions, but also extend the life of some parts. So, if you need to replace the fuse, then it is quite possible to produce, using duplicates of the same rating. A common mistake motorists is that during the installation of the battery, they confuse the poles, so you must be careful with anyone, even with such a simple task. The generator is not out of order ahead of time, do not light a car when it's below zero temperatures.

Always buy only quality parts, which is a guarantee of their correct operation. And not only them, but also of the whole system in general. So, for example, if you purchased a thin wire and plug it into a very powerful amplifier, it is likely that it will melt, and this will cause unwanted circuit. Mounting the fog lights, buy a new optional relays and fuses.

It is mandatory to pay attention to the condition of the instrument board, which should light up in the start-up time. Then, even when the engine is running, this must not light indicators which signal any faults.

A set of power tools and accessories that should be on hand at the driver

Each driver is constantly at hand must have the following tools and power tools:

1. Multimeter.
2. Insulating tape.
3. Shrink.
4. A few meters of copper wire.
5. Pliers, pliers.
6. Stationery knife.
7. Spare wheel.
8. Mount.
9. Jack.
10. Sealant.
11. Pump.
12. Cigarette lighter.
13. End wrench.
14. Lantern.
15. Universal joints, extension cords, wrenches.
16. A hammer, a chisel.

Pro Tip: What to do if in the car there was a smell of burning and smoke

If in the process of movement in the car there was a smell of smoke and soot, should stop immediately, remove the terminals from the battery and call a tow truck, because subsequent movement can be risky for life. It is important to know the basic rules and be sure to stick to them, and if any event causes confusion, it is advisable to consult a specialist.
