13.1. Detection of malfunctions in electric equipment system

GENERAL INFORMATION

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.

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.
