11. Electric equipment
Consumers unite to the plus power supply a wire, and with minus - through a car body (weight). Such method allows to reduce number of wires and to simplify installation. On cars the low-served or unattended accumulators are installed.
The electric system has 12-tivoltovy food with negative grounding and the generator, a starter, consumers of the electric power and electric chains consists of the accumulator.
Accumulator charging is made from the generator which is put in action by a belt from a pulley of a bent shaft. The starter represents the electric motor of a direct current with the mixed excitement with the electromagnetic traction relay. At start the traction relay moves the leading gear wheel to gearing with a gear wreath of a flywheel before the starter receives a power supply from the accumulator. After start of the engine the coupling of a free wheeling disconnects a starter anchor from a gear wreath of a flywheel.
When working on electric system it is necessary to be careful not to damage the semiconductor device (diodes and transistors). During the work on electric system it is necessary to fulfill the following requirements:
– in operating time of the engine do not disconnect the accumulator, the generator of alternating current or any electric sockets;
– when carrying out any works remove the negative plug from the accumulator;
– when carrying out electrowelding works on the car, switch-off the generator of alternating current and the control device.
