How to Connect the Vehicle Ground Wire?
1 Answers
When connecting the vehicle ground wire, the electrical appliances in the car are generally only connected to the positive pole, while the negative pole is connected to the car body. The following is an introduction to the knowledge of vehicle ground wires: 1. Function: The main ground wire generally refers to the battery negative ground wire, the engine-to-body connection ground wire, and the main circuit ground wire. A large number of electrical devices in the car circuit are connected in parallel and rely on these ground wires to transmit current, ensuring the effective operation of the car's electrical appliances. The main ground wire usually has a thicker diameter, and special-shaped ground connection terminals, washers, and fastening screws are used at both ends of the ground wire. Special considerations are also given to the wiring of components. If the main ground wire fails, it can affect multiple circuits. Therefore, when diagnosing faults, maintenance personnel must consider the possibility of main ground wire failure to avoid unnecessary replacement of components. 2. Introduction: It is a return line for current. The power comes out from the positive pole of the battery, passes through various switches and electrical actuators, and then returns to the negative pole of the battery through a return wire, forming a cycle that enables the electrical appliances to perform various actions and functions.
