Electrical Projects Pull the retractable cord plug out of the socket in the case. With a VOM on- R X 1 range, insert the probes into plug opening. Install the callus-smoother attachment onto nose piece and slowly turn the drum with fingers while watching ohmmeter. Do not spin it fast or developed counter voltage from the motor will give erratic readings. The reading should be approximately 12.5 ohms and at no point in a revolution should it be less than 10 ohms nor more than 20 ohms.

If reading is uniformly about 12.5 ohms, the motor is okay. If on the other hand, the reading dips to less than 10 ohms, the motor is shorted. Replace the motor. A reading of more than 20 ohms means a motor segment is open. Replace the motor. If an open circuit is indicated, the cord is defective. Replace cord.

As a final check, connect to the appliance 120V ac supply. Insert the cuticle pusher attachment and test for a handle speed of 2000 to 3000 rpm with a vibrating-reed tachometer held lightly against the tip of the cuticle pusher.
