Embodiment

[0016] First, put the leakage protector on the back of the car audio system teaching and teaching device box in the off state, cancel the fault setting of the fault setting button on the back panel of the test bench; then turn on the 220V power supply of the test bench, and then turn on the leakage protector, Keep it closed. Then turn on the ignition switch on the display control panel to start the device and start running; the teacher can set 8 different system faults according to the teaching needs. The students use a multimeter to measure the voltage and resistance between the measuring terminals on the panel to detect and analyze the fault. The location and how to eliminate it; when the teaching is completed, reset the fault button to clear the fault for next use.

[0017] Compared with traditional auto repair teaching, the present invention integrates the various components of the car audio system and is equipped with corresponding circuit diagrams. It can be used as a teach...
