How to Check an Electric Motor: Testing & Troubleshooting
WebMar 21, 2024 · 1. Confirm the motor is grounded before doing anything else. Many electric motors can run up to 240-480 volts, which is strong enough to potentially stop your heart. If the motor is not grounded, it is not safe to test. Confirm the motor is grounded using the following steps: [1] Turn the motor off. Set your multimeter to continuity mode.
