You can't ignore a couple of tie - up points on the car
  • Automotive

To uncover the hood cover or disassemble the instrument panel, we can see a lot of dense clusters of electrical lines arranged in which each line has the role of each line, but there is a line, the role is the same, that is to take the iron wire. Over a variety of switches, through the electrical actuator, to go through a line back flow line back to the negative pole of the battery, forming a cycle to produce a variety of actions and functions, the car is a single line system, that is, the majority of the lines are from the power supply, and all kinds of electric actuators are not directly to the battery. Extremely, but through the metal body of the car itself back to the battery negative pole indirectly, but to the wire connecting to the metal body of the car, we can all be called the iron line.
