Capacitor Test

CAUTION: An ohmmeter can be used to check for a shorted or open capacitor. (Isolate the component before performing continuity tests.)

WARNING: Disconnect all power sources before servicing high voltage components.

The ohmmeter should have a minimum 6V battery, and should be set on the high resistance scale.

1.Remove all power, discharge the capacitor, and disconnect all leads from the capacitor terminals.

2.With an ohmmeter set on the highest scale, measure the resistance between the two outside capacitor terminals and the center terminal. The meter needle should momentarily deflect upward to indicate continuity, and should then return to infinity. Reversing the meter leads should give the same indication.

3.If the ohmmeter indicates continuity between the capacitor terminals at all times (shorted capacitor), or if no meter deflection occurs at all (open capacitor), the capacitor should be replaced.

4.A resistance check between each capacitor terminal and chassis ground should indicate infinite resistance (regardless of meter lead polarity).

High Voltage Transformer Removal/Replacement

CAUTION: To maintain proper polarity, transformers must be installed with terminals in correct locations. Wiring must be reconnected correctly to the terminals from which it was removed.

WARNING: Disconnect all power sources before servicing high voltage components.
