How to analyze and determine the common faults in wire harness processing?

Wiring harness processing - the law of the harness burned is: in the power system circuit, where the iron, the harness burned where, burned and intact parts of the junction, can be considered as a harness iron, such as the harness burned bad bad to a wiring part of the electrical equipment, indicating that the failure of the electrical equipment.

1, the battery cable burned how to deal with: ① If the battery cable is only partially burned, then check the cable burned in contact with the contact parts, clean up the burrs after replacing the battery cable. ② If the battery cable burned out, it means that the starter motor failure. In the starter motor electromagnetic switch + pole and battery positive access to the test light, such as the test light is bright, indicating that the electromagnetic open magnetic failure; such as the test light is not bright, indicating that the starter motor internal failure. 2, generator + pole to the starter motor battery terminal between the wiring harness burned how to deal with: ① turn off the generator, remove the generator + pole of the lead, the battery + pole connected to the other end of the power line with the generator + pole contact, such as sparks appear, indicating that the generator failure. Sparks appear, indicating that the generator malfunction, such as no sparks appear, then the wiring harness failure. 3, wiring harness and relay lead burned out how to deal with: ① turn off the power switch, remove the relay, let it hang, in the relay shell and the body between access to the test light, such as light, indicating that the relay malfunction; such as the light does not come on, to carry out the following steps. ② open the power switch, such as the test light does not light up, indicating that the relay is not faulty, only replace the wiring harness can be, such as the test light indicates that the relay is faulty, the relay should be replaced.
