Analysis and judgment of common faults in wire harness machining

Time:2018-04-10 14:55:34

  The rule of wire harness burning in the wire harness factory is: where the iron is in the power system circuit, where the wire harness is burned and the junction between the burned and the perfect parts, it can be regarded as the tie line of the wire harness, if the wiring harness is broken to the wiring part of an electrical equipment, it indicates that the electrical equipment is disabled.

  One, the battery line is burnt out

  1, if the battery line is burned out, check the parts that are contacted with the cable burn out and replace the battery line after burrs.

  2, if the battery line is burned out, it will indicate that the starter is out of order. The test lamp is connected to the pole of the starter electromagnetic switch + pole and the positive pole of the battery, such as the light of the test lamp, indicating the fault of the electromagnetic magnetic opening; if the test lamp is not bright, it shows that the internal fault of the starter is occurring.

  Two. The wiring harness between the generator + pole to the pole battery wiring harness breaks down the forward motor, dismantle the generator + polar lead, and connect a power line between the battery and the pole, the other end contact with the generator + pole, if the spark appears, indicating that the generator is in trouble, if no spark appears, the wiring harness appears malfunction.

  Three, wire harness and relay lead burn out

  1, turn off the power switch, dismantle the relay, let it hang out, the relay housing and the body between the body access light, such as light, indicating the relay failure; if the light is not bright, the following steps.

  2, turn on the power switch. If the test lamp is not bright, it means that the relay is free from failure. Only the wiring harness can be replaced. If the test lamp indicates that the relay fails, it should replace the relay.
