General method of automotive relay radio frequency filter

　　1 . Look at the full picture first. Fragment the separate system

　　usually. The total power and power switch of each automotive electrical system is public. Any system should be a complete circuit, which should follow the principle of circuit.

　　2 . Analyze the working process of each system and the connection between each other

　　Before analyzing an electrical system, it is necessary to know that the electrical system contains automotive relays, switches, function, role, and technical parameters of each component. During the analysis process, special attention should be paid to the working status of the switch and relay contacts. Most electrical systems change the circuit through the different working status of the switch and relay to achieve different functions.

　　3. Through the analysis of typical circuits, it plays a role of bypassing the category

　　There are many parts of the circuit schematic diagram of different types of cars. In this way, through a specific example, one derived and compared with comparison. Touching by aspects can master some common rules of the car, and then guide these commonality as a guidance to understand the circuit principles of other models. You can also find more commonality and differences between various models.

　　The universality and professional production of automotive relays make the vehicle circuit of the same country's vehicle circuit roughly the same. If you master the characteristics of automotive relay and switch, you can roughly understand the characteristics of a certain model circuit. Features.
