Search for a faulty consumer in the following sequence:
- remove the ground wire from the negative terminal of the battery. Connect the multimeter between the negative terminal of the battery and the wire removed from the battery. If the device shows the presence of current, then there is a faulty consumer in the network;
- connect the ground wire to the negative terminal of the battery. Open the fuse box cover and remove one of the fuses. Connect a multimeter to the free contacts. If there is no current in the circuit, then the circuit being tested is OK. A small current is not a cause for concern. Devices such as the on-board computer, clock, radio and alarm are constantly under voltage. The amount of electricity they consume is much less than in the presence of a defective power consumer;
- repeat similar measurements on the mounting block until your multimeter shows an increased current value in this circuit. Using the electrical connection diagram in this manual, you can determine which consumers are included in this circuit;
- consistently disconnect the consumers located in the circuit being tested, measuring the current each time. When the multimeter does not show the passage of current, you can assume that you have found a faulty element.
