How to check for short circuits with a multimeter?
The short-circuit resistance value of the capacitor is zero; the resistance of the transformer and motor coil touching the shell is also zero;
Short circuit between two insulated coils, etc. Some short circuits cannot be measured, such as short circuits between turns of the coil.
Suggestion:
The resistance has no polarity. Use a multimeter to measure the voltage of the electron. The red test lead is connected to the positive, and the black test lead is connected to the negative. The multimeter shows a positive number, and vice versa. Buzzer gear measurement, if the multimeter makes a beeping sound, it is judged that it is short-circuited
