What are the wires for a cigarette?

Battery - capricious thing: some batteries are sitting down from old age, others - because of dilapidated wiring, and others are discharged because of the negligence of the car owner. Anyway, and every motorist should have wires in the trunk for a lightening. Quite often problems with charge arise in the winter, when the engine is difficult to turn the oil thickened in the crankcase, and the battery can not provide the necessary charge due to the frozen electrolyte.

Old carburetor models can be tried with a jolt, but for modern cars this method is not suitable, because because of the large volume of electronics and different modern utensils, only the wires for the lightening will help.

Today they are freely sold in any specialized store, however they can be made independently. It is enough to take an aluminum wire or a copper wire, get special test leads and crimp them.

If the engine does not start, and there are no wires, then you can find an alternative as a tow rope or self-made wires. However, it is not recommended to resort to such methods, due to poor contact , the battery may fail, and the probability of electric shock is high.

It is important that the electrical wires are connected according to the specified polarity. Otherwise, the car electronics may be damaged.

It is recommended to connect it as follows: the positive terminal of the ground battery is connected to the positive terminal of the charged battery; The minus terminal of the dead battery is not used, one end of the wire for the lighting should be fixed to the body of the faulty machine, and the second - to the terminal of the charged battery.

If you connect the negative terminals, you can quickly discharge the charged battery. After the correct connection, the car starts. Do not immediately start a faulty car, you need to give a little recharged battery. The car with the charged accumulator is muffled and it is started faulty. After the factory, the wires for the lighter must be removed in the reverse order: first the negative terminal is released and then the positive terminal.

It is worth remembering that when starting the engine, large currents are created, so it is very important to select the correct cross-section of the wires. It is calculated according to the material. If copper is used, then 3 mm2 will suffice for lightning, if the wires are aluminum, then the cross section must be at least 4 mm2. Why is that? The fact is that each material has its own resistivity, which is reflected in a special table. The resistivity of copper is less than that of aluminum, so the cross-section of the copper wire is chosen smaller.

If it is decided to use a cable as the cable for a cigarette, you should pay attention to the insulation. In order to use it, you must arm yourself with a knife and swing both ends. Well, if each vein of the wire is isolated, but there are tow cables that are released without insulation, in this case care must be taken to ensure that there is no ground fault or between the plus and minus.
