14.1.1. Introduction

With плюсовым the power supply consumers incorporate a wire, and with minus – through a body of the car (weight). Such method allows to reduce number of wires and to simplify installation. On cars are established малообслуживаемые or unattended accumulators.

The electric system has 12-tivoltovoe a food with negative grounding and the generator, a starter, consumers of the electric power and electric chains consists of the accumulator.

The accumulator gymnastics are made from the generator which is put in action by a belt from a pulley of a cranked shaft.

The starter represents the electric motor of a direct current with the mixed excitation with the electromagnetic traction relay. At start the traction relay moves a leading gear wheel to gearing with a gear wreath of a flywheel before the starter will receive a food from the accumulator. After engine start муфта a free wheeling disconnects an anchor of a starter from a gear wreath of a flywheel.


At performance of works on electric system it is necessary to be careful not to damage the semi-conductor device (diodes and transistors). At work on electric system it is necessary to fulfil following requirements:

– In an operating time of the engine do not disconnect the accumulator, the generator of an alternating current or any electric sockets;
– At carrying out of any works remove the negative plug from the accumulator;
– At carrying out of electrowelding works on the car, disconnect the generator of an alternating current and the control device.
