How do you check if an electric motor is good or bad?

Use a multimeter or an ohmmeter to test the voltage of the electric motor. If there is no resistance or the resistance is uneven, the motor is likely faulty. Check the bearings to make sure they can spin freely. If they can't, lubricate them.

How many ohms should a motor read?

With a multimeter, measure the resistance between motor frame (body) and earth. A good motor should read less than 0.5 ohms. Any value greater 0.5 ohms indicate trouble with the motor.

What ohms should a motor read?

The reading should be between 0.3 to 2 ohms. If it is 0, there is a short. If it is over 2 ohms or infinite, there is an open. You can also dry the connector and retest to possibly get more accurate results.
