Technical characteristics





Wires

The cross-section section of a wire gets out depending on need for power supply of each consumer: the control bulb costs a wire the in thickness 0,5 mm 2, and the wire in thickness of 16 mm 2 is necessary to a starter. Too thin wire heats up, and tension falls. Then instead of desirable 12 In, for example, on headlights, arrives, maybe, only 10 or 9,5 In – light becomes dim.
