Repair and car operation

Before to try to define a malfunction source, in the beginning study the corresponding scheme of electric equipment for receiving idea of the elements established in this chain. The circle of possible sources of malfunction can be narrowed if to check functioning of other elements entering into this chain. If some elements or chains выхолят out of operation at the same time, a problem, obviously, consist in a safety lock, the general for these chains or elements, or contact to a body.

Electric problems are usually caused by the simple reasons, such, as the weakened or rusted sockets, absence of contact to a body, the fused safety locks, the melted burned-through crossing point or the faulty relay. Visually check a condition of all safety locks, wires and sockets in the failed chain before to start check of other elements. Use electric equipment schemes for definition of what of trailer clips are necessary for checking for detection of a source of malfunction.

The main tools necessary for detection of a source of malfunction, the tester or the voltmeter (a bulb on 12 volts and pair of wires with щупами on the ends, also can be used for carrying out some checks) are; ohmmeter; the battery and a set of wires with щупами, a cap puncture, it is desirable with the automatic switch or a safety lock which is used for round of checked wires or elements.

For detection of the reason of unreliable work any of elements (usually because of bad connection or pollution of contacts, or), it is possible to inspect the damaged isolation by stirring of wires. It is necessary to shake a wire by a hand to check, whether there is a malfunction at wire movement. Such method it is possible to narrow a circle of possible sources of malfunction to any wire.

Along with problems because of bad connection of the wires, two main types of malfunctions can take place in electric equipment system – the opened chain or short circuit.

Problems with the opened chain appear as a result of break in an electric equipment chain that interrupts current course. The opened chain will cause shutdown of an element of electric equipment.

Problems with short circuit are caused by short circuit of a site of a chain that leads to leakage of a current from other chain, usually directly on a body. Short circuit is usually caused by a rupture of isolation of wires that allows a wire to concern other wire or any earthed element, for example a body. Short circuit usually leads to a peregoraniye of the corresponding safety lock.
