11. Electric equipment

GENERAL INFORMATION

The system of electric equipment has working tension of 12 Volts and uses
negative grounding. A food for headlights and all other elements of electric equipment arrives from the lead-acid accumulator which is recharged from the generator.

In this chapter repair and service operations for the various elements of the electric equipment which have not been connected with the engine are described. Information on repair and service of the accumulator, the generator, the distributor of ignition and a starter can be found in the corresponding chapter.

It is necessary to notice that at work with system of electric equipment it is necessary to disconnect a wire of the negative plug of the accumulator for prevention of short circuit and (or) ignitions.


Prevention

If the stereoplayer of your car has coding system, check, whether you know a code of activation of a player before an accumulator detachment.


Detection of malfunctions in electric equipment system

The typical electric chain consists of an element of electric equipment, switches, the relay, engines, the safety locks, burned-through crossing points or automatic switches and wires and connections which connect all elements among themselves and connect them to the accumulator and (mass) of the car. To simplify process of troubleshooting in the end of this chapter electric circuits of system of electric equipment of the car are given.

Before the beginning of check of a faulty chain, in the beginning study the schematic diagram of this chain to understand from what elements it consists. The source of malfunction can be found quicker if to define, what of elements of this chain work normally. If some elements or chains fail at once, the problem, possibly, consists in the fused safety lock or bad grounding as often one safety lock is responsible for some chains.

Problems with work of system of electric equipment are usually caused by the simple reasons, such as the oxidized or unreliable contacts, the fused safety lock, the fused burned-through crossing point or the faulty relay. Visually check a condition of all safety locks, wires (if it is possible) and connections in a faulty chain before the beginning of check of other elements of this chain. If you are going to use instrumentations, use schematic diagrams to define, what connections are necessary for checking for failure detection.

The main devices necessary for search of malfunction in a chain of electric equipment, are the voltmeter (or a bulb on 12 Volts with connecting wires), the device for check of integrity of chains, the accumulator with connecting wires and a cap wire, it is desirable with the automatic switch which can be used for parallel connection to a chain. Before the beginning of search of malfunction with use of the control and measuring equipment, study schematic diagrams to define connection points.

System of electric equipment of the engine

The system of electric equipment of the engine includes ignition system, system of a charge of the battery and system of start-up of the engine.

At care of electric equipment observe the following rules.

At the idle engine it is forbidden to leave ignition included for a while bigger 10 minutes.

It is forbidden to disconnect cables from the battery on the working engine.

At emergency start-up of the engine from the battery of other car observe polarity of connection of the battery

Always disconnect the battery from weight first of all, and connect to weight in the last turn.
