(5) If meter displays high resistance and remains there, the capacitor is
internally shorted and must be replaced.
(6) If the meter does not show any resistance, the capacitor is open and
must be replaced.

Inspection
A capacitor can retain a high electrical charge. Touching the
terminals of a charged capacitor can result in severe
electrical shock and skin burns. Always ground the termi
of a capacitor as soon as they are exposed.
(1) Remove capacitor boots from capacitor bodies.
(2) Using jumper cable, make contact with capacitors and casi
(3) Check capacitor for cracks, evidence of overheating, and
visible damage. Replace if damaged.

(4) Check that top of capacitor is flat. If the top is “ballooned”, it has
failed and must be replaced.
