Due to the different drawing methods, symbol labels, text labels and technical standards of automobile circuit diagrams in different countries, the automobile circuit diagrams drawn by automobile manufacturers are also quite different. Therefore, before reading different series of automobile circuit diagrams, you need to understand the characteristics of the circuit diagrams and master the relevant knowledge of automobile circuit diagrams. The basic method of reading the graph.
1. familiar with the drawing rules of automobile circuit diagram
In the circuit diagram of the entire automobile, the electrical appliances are from left to right (the power supply is on the left, the electrical equipment is on the right, and the local circuit is in the schematic diagram.
In, 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), draw the circuits of each electrical system together as much as possible.
2. Familiar with the symbols and meanings of automotive circuit components
Be familiar with the name of automobile circuit diagram, clarify the meaning of electrical symbols, text labels, codes and abbreviations, and establish one-to-one correspondence between components and graphic symbols. Many automotive circuit diagrams are represented by electrical symbols. Electrical symbols are simple graphic symbols that can only roughly show the appearance of electrical appliances. The name of the appliance is described in text on or next to the graphic symbol. The electrical symbols drawn by different car manufacturers vary, some simple, some complex.
