Automotive Wire Harness did not select the wire according to the rules when changing the wire (the wire was too thin), and a large voltage drop occurred during the high current passing period, resulting in heat generation, resulting in the gradual aging and damage of the wire skin; Careless installation of the battery, reverse connection of the positive and negative polarities, short circuit in the alternator, damage to each insulating gasket and insulating sleeve, and reverse connection of the alternator magnetic field line and grounding wire will cause the Wiring Harness to burn; The automobile wiring harness is often fixed with a thin iron card. Its edge is sharp like a knife edge, and the surface of the iron card is not insulated. The vehicle oscillates and fluctuates during long-term driving. burn; When the automobile wiring harness is temporarily connected to the electrical equipment, the current inlet and outlet of the fuse are not understood, that is, the power cord is drawn out at will, or after the fuse is burned out, the fuse of the same specification is not replaced as required, or the thick copper wire is used instead of the fuse. Lose the protective effect and burn the Wire Harness; The two terminals of the ammeter are often made of plastic insulating sleeves. The plastic heat dissipation is poor, and it must withstand both current and fluctuations and oscillations. If the ammeter wiring is loose or the contact is not good, the temperature will rise, resulting in plastic melting and grounding. The incineration of wire harnesses; The connection of the post is unreliable, and a large voltage drop occurs and generates heat. After a long time, the insulating gasket will be damaged and the ground will be short-circuited. Note that the posts behind the ammeter and other surfaces should be well connected, and the wire connecting screws fixed on the wiring board of the frame should not be too long to avoid burning the wiring harness due to grounding.
