Onboard electric equipment

General information and precautionary measures

 Before starting service of components of systems of onboard electric equipment study requirements of safety regulations during the work with electric devices.


The car is equipped with a 12-voltny onboard power supply system with grounding on a negative pole. Supply of electricity to illuminants and other consumers is carried out from the battery of lead-acid type which recharge is made from the generator of alternating current.

The description of procedures of repair and service of the electric components established on the car and which do not have a direct bearing on operation of the engine is provided in the present Chapter. Information on service of such units as the battery, the ignition distributor, the generator and a starter is provided in the Head Elektrooborudovaniye of the engine, devoted to systems of electric equipment of the engine.

Before starting service of components of onboard electric equipment, in order to avoid receiving electric shock, or ignition as a result of casual short circuit, it is necessary to disconnect a negative wire from the battery. Regularly check a condition of plaits of an electrical wiring and reliability of their fastening in intermediate clamps, collars and bindings. Watch that isolation of wires was not wiped at contact with the components located in the neighbourhood.

 The models of cars considered in the present manual are equipped with system of additional safety (SRS). Before starting performance of any works near the block of a safety cushion, a steering column or the dashboard, disconnect SRS in order to avoid receiving injuries at its casual operation (see the Section System of Additional Safety (SRS) - the device and the principle of functioning)! It is easy to distinguish an electrical wiring of a chain of SRS on yellow color of isolation.


If the stereosystem established on the car is equipped with a security code before disconnecting the battery make sure that have the correct combination for input of the audio system in action!
