15. CAPACITOR
REPLACEMENT
To replace the capacitor, follow the step-by-step procedures listed below.
CAUTION: DISCONNECT BOTH AC INPUT AND DC OUTPUT CORDS FROM ALL
POWER SOURCES. POWER IS NOT NEEDED FOR THIS REPLACEMENT.
1. Disconnect the charger’s AC input cord from its outlet and the DC output plug from the
battery receptacle.
2. Remove the Phillips screws that retain the cover and then remove the cover and locate the
capacitor at the rear of the case assembly as shown in Figure 15.
DANGER: RISK OF ELECTRIC SHOCK! HIGH VOLTAGE! THE VOLTAGE AT THE
CAPACITOR TERMINALS CAN BE AS HIGH AS 660 VOLTS WHILE THE CHARGER
OPERATES. USE EXTREME CAUTION WHEN NEAR THE CAPACITOR TERMINALS.
WARNING: THE CAPACITOR STORES AN ELECTRICAL CHARGE AND MAY NOT BE
FULLY DISCHARGED! TO AVOID AN ELECTRICAL SHOCK FROM THE CAPACITOR
YOU MUST DISCHARGE IT COMPLETELY.
3. Discharge the capacitor by adjusting your multi-meter to its highest DC voltage scale and
then touch and hold the test leads to the capacitor terminals for three seconds. Follow this
by shorting across the terminals with an insulated metal tool. A capacitor discharged in this
manner will be safe to touch.
4. Carefully remove both of the quick disconnect female terminals. Use a large needle nose-
pliers or similar clamping tool that you feel comfortably in control of and grasp the body of
the quick disconnect terminal to remove it. Do NOT pull directly on the copper wire or a
broken connection could occur.
5. Loosen the screw on the back of the enclosure that retains the capacitor strap. When the
capacitor strap is loose, the capacitor will slide out the top of the strap. Install the new
capacitor into the capacitor strap and retighten the screw to hold the capacitor in securely.
6. Carefully reconnect the female quick disconnect female terminals to the new capacitor,
inspecting them for proper connection.
7. Replace the cover and tighten the cover screws.
