Troubleshooting - General
The structure of electrical circuits includes consumer, switches, relays and wires connected on the attached chart (See below.). Before you begin troubleshooting should examine the scheme and to determine the possible source of the fault. For example, the task of troubleshooting much easier, if you can check whether your other customers, either directly or indirectly connected to a suspected circuit. If there is a failure of a number of users, the most likely cause is an open connection to the mass or blown fuse. Usually an electrical failure caused by loose connections or corrosion, blown fuse or melt jumper. Troubleshooting is usually performed with a tester (voltmeter) or a control lamp, which are connected between a portion affected circuit and well buffed weight. By connecting a tester or a lamp in series circuit can detect the faulty circuit portion which is detected by a power outage, or the extinction of the lamp.

To search for a short circuit in the wires should be to get the fuse in the circuit under test and connect the lamp gap or voltmeter. On shorting the mass points tanning lamp wires under shaking from side to side (tester should show voltage). When checking should bear in mind that some consumers are supplied at the position of the ignition key to the ACC or Run. To check the reliability of the connection with the mass is connected via an ohmmeter (or via a control lamp with battery) checks the connection wires with a mass and a good portion of the stripped weight. If the ohmmeter show the chain (or the lamp lights), then connect to a reliable weight. Otherwise contact with a mass of broken. Keep in mind that most of the mass is the reverse pathway, connecting the circuit to the negative terminal of the battery. Therefore, violation of connection with weight, or break in the chain of the reverse current to the battery, it may be the main reason for the refusal.
