In the part of the car with poor grounding, use gauze to polish and clean it, then apply special conductive glue, and finally tighten the fixing bolts or plug in the connector to solve the problem. Grounding is to ensure that the engine can have sufficient voltage and current.

If the car is poorly grounded, there will be six phenomena. The first is that it is difficult to start. After the car is parked overnight, it will be found that it cannot be started the next day, but the voltage of the battery is normal, and it will take a few minutes before it can be started. The second is that the fault sometimes does not exist, and the engine is turned off irregularly during driving, or it can be turned on occasionally after the engine is turned off, and occasionally it cannot be turned on. The third is abnormal instrument indication. The fourth is that abnormal sparks are generated, and it can be intuitively seen that sparks are generated during contact. The fifth is that the car will move back and forth when accelerating. This situation is specifically caused by poor grounding of the fuel pump. The sixth is that the car will vibrate violently, which is usually caused by the loosening of the negative electrode or corrosion of the contact surface.
