Detection of faulty consumer



When working on the eve of battery stops giving current perhaps it unloaded for the night is in faulty consumer. To verify, first measure the current in the circuit. It should identify the failed consumer.

SEQUENCE OF WORK
1. Remove the wire from the negative terminal of the battery, connect a multimeter between the negative pole of the battery and "weight". If the device shows the current value exceeds 20 mA, the circuit is faulty consumer. Before testing, make sure that all consumers are switched off.
2. Connect the cable to the negative terminal, open the fuse box and remove one fuse. Connect the fuse wire to the terminals of the tester. If the instrument does not show the current circuit of the consumer is not damaged. A small current is allowed. Devices such as the clock, radio or alarm continuously consume power from the battery. However, in their current circuit is much lower than the defective unit.
3. Continue to measure the fuse until clarified device in the chain which is a large current. The table of safety locks can figure out what devices are connected through it.
4. Disconnect the device turns on the circuit and each time checks should be current. When the tester is no longer shows the current device is found defective.
