How to Discharge a Capacitorby Contributor
Before working on any motor, be sure you discharge the capacitor. Capacitors store energy and can pack a serious and potentially dangerous jolt of electricity.
Unplug the power feeding the motor.
Pick up a 20,000-ohm, 2-watt wire resistor at an electronics store. Be sure it's a wire-wound resistor.
Stick a jumper on each end of the resistor, using two jumpers with alligator clips.
Clip one free end of a jumper to the flat edge of a standard screwdriver with an insulated handle.
Attach the final jumper to one terminal of the capacitor.
Touch the tip of the screwdriver to the other terminal.
- check If there are more than two terminals on the capacitor, be sure to attach the clip to each one and discharge all of them.
- close If you don't fully understand this procedure or it makes you uncomfortable or you're unsure if you did it correctly, consult a licensed electrician.
