Capacitor Testing
1. Charge the capacitor for 10 seconds using a 12 volt battery
by connecting the positive (+) lead to the Red/White wire
and the negative (-) lead to the brown wire.
2. Monitor the capacitor voltage with a multimeter. The
voltage should slowly drain down from the initial charge.
If the cap does not hold a charge or drains rapidly, replace
the component.
