The introduction of automobile electrical maintenance is very simple. First of all, you should understand the structure and principle of the car, and then understand the meaning of each symbol in the car circuit diagram. These are all rote learning. Of course, with this foundation, you should learn to use it flexibly. The most important thing left is to know how to disassemble and assemble parts. For example, you need to know how to disassemble the dashboard, how to disassemble the airbag and how to put it back after disassembly.
In fact, in auto repair, painters are the easiest to develop themselves, because mechanical and electrical maintenance involves parts, and the parts of each model are different, including genuine products and defective products. You will invest a lot in opening a repair shop in the future. But as a painter, you can open a paint repair shop in the future, as long as the source of paint is solved, and the paint is universal, and there is no need to divide the model. As long as the mixing is good and the technology is good, you don't have to worry about color difference and paint loss.
