When many friends drive a car, they will encounter such a situation. When the car is opened for a short period of time, it will automatically shut down, and when it starts again, it will turn off. This may be due to the aging of the engine wiring harness. The temperature of the engine compartment of a car is very high, plastics will inevitably release chemical substances such as plasticizers. These chemicals react with the copper core wire, causing the plastic strength to decrease and the resistance of the copper core wire to increase, resulting in aging of the wire harness.

The safest way is to change. In fact, there are few wire harnesses that will not age. The wire harness on the engine ages the fastest, but it is sheathed outside and covered with tape inside. Basically no short circuit. In addition, the most dangerous is the headlamp wiring harness, which is easily corroded by the electrolyte after the battery is buzzed, and is easily worn by the body under the air filter to rub the skin.

Visual inspection before replacement. The new wiring harness model should be consistent with the original model, lead terminals and wires connected reliably, the Secretary with a pull and pull each connector and the conductor is loose, off phenomenon. Compare the new harness with the original harness, such as: the size of the harness, the wire terminal connector, and the wire color should be basically the same. Where there are doubts, the Division - with a multimeter to test, confirm that after the wiring harness is intact, Division Division 1 is replaced.

Harness installation. The connectors, plugs, and sockets of each electrical device must correspond to the sockets and plugs on the harness. After connecting the connecting wires with the electrical equipment, there must be a certain margin, and the wires are not pulled too tightly.
