Minus pole, and red

If nothing helps the car, it remains only to connect through the cigarette lighter, to the battery of another car. Copper wires with a section of 16 square millimeters are used, five millimeters in diameter. It is best to buy an adapter with silicone isolation, which do not freeze during the cold and are equipped with a special soldering, and not just isolated with electrical tape or compression. In order not to confuse the pole, the clamps must be marked by each with their own color. Black color means a minus pole, and red plus. It is desirable that the color is marked not only on the clamp, but also on the wire itself.
