The capacitor is an electrical storage device that stores an electronic charge.
ALWAYS discharge the capacitor before testing or handling. Failure to discharge
the capacitor may result in bodily harm and/or damage to test equipment.
NOTE: For this procedure, refer to FIGURE 7.6 on page 39.
1. Remove the cabinet. Refer to Removing/Installing the Cabinet on page 25.
2. Remove the two wire connectors from the capacitor.
3. Discharge the capacitor by placing a screw driver with an insulated handle across the
wire connectors on the top of the capacitor.
4. Connect the leads of a capacitance meter to the terminals on the capacitor.
NOTE: For the capacitor to be within specification, the meter should read 3 mfd +10% or –5%.
5. Perform one of the following:
• If the capacitor is out of specification, replace the capacitor. Refer to Replacing
