Car circuit repair can generally be divided into the following parts. ① power supply system. Mainly includes the battery, generator and its voltage regulator. The power supply is 12V low voltage direct current. Automotive electrical repair words include circuit repair, light bulbs, center console dashboard and all electrical items repair. Automotive electrical and mechanical repair of electrical systems are mainly lighting systems, electronic ignition systems, weak multimedia and audio systems.
Automotive electrician's main responsibilities? Automotive electronic control system inspection and repair, including generator, starter motor, ignition system, engine electronic control unit, computer testing, accident car or fire car wiring and so on. Automobile electromechanical repair is based on automobile non-electrical and vehicle electrical appliances and wiring repair, that is, mechanics including mechanics and electricians. There is a difference with the auto mechanic, even if they are all affiliated with the electromechanical industry.
1 Familiar with the circuit diagram, can read the automobile circuit structure. 2 Understand a variety of electrical parts symbols, role and function. 3 To determine the fault phenomenon failure point in the circuit. This article first explains the structure of the automotive electrical system, and then analyzes the electrical equipment and engine failure causes, and finally, puts forward the automobile routine maintenance measures. In order to be able to do a good job of automotive electrical equipment failure maintenance to provide help. Why do you need to measure online, because the measurement if the power off over, equivalent to the principle of reset to the body computer power cuts, interested friends can be tested separately to compare the power off connecting the multimeter and connecting a good multimeter and then separate the negative line test results are not the same, especially some of the tiny leakage test, this method is more useful.
Liberation trucks and imported Toyota, Blue Bird sedan electrical equipment based on a comprehensive and systematic introduction to its structure, principle and troubleshooting methods and maintenance operation technology. Electrical equipment maintenance generally includes: daily inspection tours, inspection and testing on a regular basis, a good plan to overhaul, regular maintenance and so on. Ignition system should pay attention to the problem First of all, in the maintenance process, be sure to ensure that the electronic ignition system hitch is good.
