Description of automobile basic circuit diagram

Due to the different drawing methods, symbol labels, text labels and technical standards of automobile circuit diagrams in various countries, the automobile circuit diagrams drawn by automobile manufacturers are also very different. Therefore, before reading different series of car circuit diagrams, you need to understand the characteristics of the circuit diagrams and master the knowledge of car circuit diagrams. The basic method of reading.
Familiar with automotive circuit diagram rules
In the circuit diagram of the car, electrical appliances are used from left to right (the power supply is on the left, the electrical equipment is on the right, and some circuits are in the schematic diagram.
In the middle, the signal input terminal is on the left and the signal output terminal is on the right), from top to bottom (the live wire is on the top and the ground wire is on the bottom), the circuits of each electrical system are pulled together as much as possible
2. Familiar with the symbols and meanings of automotive circuit components
Be familiar with the name of the automobile circuit diagram, clarify the meaning of electrical symbols, text labels, codes and abbreviations, and establish a one-to-one correspondence between components and graphic symbols. Many circuit diagrams on cars are represented by electrical symbols. Electrical symbols are simple graphic symbols that only roughly show the appearance of the appliance. Use the text on or next to the graphic symbol to explain the name of the appliance. The electrical symbols drawn by automakers vary, some simple and some complex
