1, electronic wire harness burnout detection and judgment of the electronic wire harness burnout, are sudden, and burning speed, burned lines, generally no insurance device. Electronic wire harness burnout is the law of the power supply system circuit, which point latch, electronic wire harness will burn to where the burnout and intact parts of the intersection, the wire can be considered latch; if the electronic wire harness burnout to a wiring part of the electrical equipment, it indicates that the electrical equipment failure.

  2, the line between the short circuit, break, poor contact detection and judgment of the fault

  Electronic wire bundle by the external extrusion, impact, causing damage to the wire insulation layer in the power supply harness, resulting in a short circuit between the wires, so that some electrical equipment out of control, peace wire fuse.

  Judgment, you can disassemble the electrical equipment and control switches at both ends of the electronic wire harness plug, with a meter or test light to detect the short circuit in the line.

  Wire break failure, in addition to the obvious fracture phenomenon, rare failures occur between the wire and wire terminals. Some of the wire break, the outer insulation layer and wire terminals intact, but the core of the wire and wire terminals have been disconnected. Judgment, can be suspected of disconnection of the conductor high-temperature wire and wire terminals to do pull test, pull test process, such as wire insulation layer gradually become thin, can confirm the wire has been disconnected.

  Poor line contact, the fault occurs more in the plug connector. When the fault occurs, it will cause the electrical equipment does not work properly. Judgment, turn on the electrical equipment power, touch or pull the electrical equipment of the plug, when touching a plug, the work of the electrical equipment suddenly normal, suddenly abnormal, marked the plug has a fault.
