GENERAL INFORMATION

Consumers unite to the positive power supply a wire, and with minus – through a car body (weight). Such method allows to reduce number of wires and to simplify installation.

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

For protection of electric chains safety locks which color corresponds to current of protection of a safety lock are used. Serviceability of a safety lock is determined by presence of the wire conductor connecting contacts of a safety lock.

During the work with electric an oborudova niy remove a weight wire from the accumulator to prevent a possibility of short circuit of electric chains.

The electric equipment of the engine includes system of ignition, charging and start.

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 of the engine 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 not to damage semiconductor devices (diodes and transistors) 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 electronic control device;
  – do not allow operation of the engine with the generator disconnected from electric system;
  – do not check operability of the generator, closing its output contacts on weight.
