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.

First, the battery cable burned out ① such as battery cable only partially burned out, then check and cable burned out in contact with the production parts, clean up burrs after replacing the battery cable. ② such as the battery cable burned out, it shows that the starter motor failure. In the starter motor electromagnetic switch + pole and battery positive access to the test lamp, such as the test lamp is bright, indicating that the electromagnetic open magnetic failure; such as the test lamp does not light, indicating that the starter motor internal failure.

Second, generator + pole to the starter battery terminals between the harness burned out stop the generator to remove the generator + pole lead, battery + pole with a power line between the other end and generator + pole contact, such as sparks appear, indicating that the generator malfunction, such as the absence of sparks appear, it is illustrated that the wiring harness malfunction.Third, the wiring harness and relay leads burned out ① turn off the power switch, remove the relay, let it hang, between the relay shell and the body access to the test light, such as the light is bright, indicating that the relay malfunction; such as the light is not bright, 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.-4、About BBC Electronic Products Network platform related to the introduction and sales of products briefly: BBC Electronic Products Network - a professional agent / production / sales of a variety of {connectors | wiring harness | wire and cable products}; if you have a related [connectors | wiring harness | wire and cable products] purchasing / sourcing needs or would like to buy / to understand which connectors | wiring harness | wire and cable products we can provide solutions, please contact the following Division Division I business personnel!
