~1min read
PROCEDURE

1. Using an ohmmeter, check continuity between the commutator and the rotor core. If there is continuity, replace the rotor.

2. Using a special tester, check the rotor coil.
If there is a short circuit, replace the rotor. If the steel strip held over the rotor vibrates, the rotor coil has a short circuit.

3. Using an ohmmeter, check continuity between the commutator segments. If there is no continuity, replace the rotor.
