13.1.3. Search of a source of malfunction in electric equipment system


For simplification of search of sources of malfunction at the end of this Chapter electric equipment schemes are provided. Study them before diagnostics beginning.

Malfunctions in system of electric equipment are usually caused by the simple reasons, such as the bad connection, the fused safety lock or the bad relay. Check these elements first of all.

Tension check

Lack of tension on an electric equipment element is caused by bad connection more often. Check a chain site between the accumulator and an electric equipment element on integrity by means of the voltmeter.

Search of short circuit

For stock-taking of short circuit remove a safety lock and connect a control bulb or the voltmeter to plugs of connection of a safety lock. Tension should not be.

Move a checked wire here and there. If the bulb lights up, means, there is a short circuit. The same check can be carried out on any element of electric equipment, even the switch.

Check of reliability of grounding

Disconnect the accumulator and connect one wire of a control bulb with the power supply to "weight", and second "weight" to a wire of a checked element. If the bulb lights up, means, grounding as it should be.
