Is it often related to car wiring harnesses?

Cars often burn insurance and have a certain relationship with the wire harness. What is the relationship? Please look down:

1. We often use a cigarette lighter to charge the phone. When we plug in the charging device, the fuse is broken. This is caused by the connection of the car harness connected to the cigarette lighter. The cigarette lighter is connected to the car wiring harness. A plug must be plugged in to solve the problem of burning the fuse.

2. The plug of the car harness is connected to the virtual one. When we turn on the vehicle appliance, power is increased due to the heat generated by the virtual position, and the load is applied to the car fuse. Therefore, the fuse is not protected by the car fuse and no fuse is provided. Automatically disconnect.

3, other electrical appliances, due to different power consumption, the current load is greater than the safe load, the insurance will be broken. This phenomenon is normal, or insurance can increase by 5A. Basically, vehicles are mainly used for harness roads. Big 5A is no problem, in addition to the insurance that burns often, such as headlights, many are not caused by headlight problems, but the power generation is too large, then the power generation system or the modified light bulb is too strong, then one is the circuit system Short circuit, insurance has been inserted and burned, and the other is intermittent failure. For example, the power cord wears out at some point, but it is prone to problems only when the vehicle is starting or bumping.
