10.1. Features of a design

The electric equipment of the car is executed according to the single-wire scheme: negative conclusions of sources and consumers of the electric power are connected to "weight". Function of the second wire is carried out by a car body. Electric chains of a control system are executed by the engine according to the multiwire scheme and connected to "mass" of the car. A food of consumers is carried out from the storage battery (at the idle engine) and the generator (at the working engine).

For switching of the main chains of the car the combined switch (lock) of ignition consisting of a contact part and the mechanical anti-theft device with the lock serves. Switches of external lighting and antifog light are incorporated in the control unit external lighting.

The switch of operating modes of the electrofan of a heater, the switch of heating of back glass and the switch of the alarm system are located on an overlay of the console of the dashboard. Switches of headlights, indexes of turn, a cleaner and a washer are incorporated in the block of podrulevy switches. Electroconsumers of big capacity join via electromagnetic relays.

Schemes of electric equipment of the car are provided in the book end.

Preventions Any works with electric equipment of the car carry out only at the disconnected storage battery. To disconnect or connect the storage battery it is possible only at the switched-off ignition. At check of chains of electric equipment it is forbidden to close on "mass" of a wire (to check serviceability of chains «on a spark») as it can lead to failure of elements of electric equipment. It is forbidden to apply the safety locks not provided by a design of the car or calculated on a bigger current, and also to use instead of safety locks a wire. At replacement of safety locks it is forbidden to apply screw-drivers as it can lead to short circuit in electric equipment chains. It is forbidden to disconnect the storage battery at the working engine in order to avoid failure of a regulator of tension and elements of the electronic equipment of the car. At carrying out electrowelding works on the car it is necessary to disconnect wires from plugs of the storage battery, the generator and the controler. Regularly clear plugs of the storage battery and tips of wires of oxides and dirt. At additional charge of the storage battery by means of the charger disconnect wires of electric equipment of the car from battery plugs.
