Since it worked before but not now, it must be that one or some components in the circuit are damaged, the battery is dead, etc. These faults cannot be seen from the picture, and the electrical schematic must be correct.

According to my test, whether it is connected to AC power or battery power, the voltage of this device is as shown in the figure E, and the B pole is 12V. How can I reduce the voltage of the B pole?
