Capacitor

Capacitor Resistance TEST

a. Good Condition - indicator swings to zero and slowly

returns to infinity. (Start capacitor with bleed resis-

tor will not return to infinity. It will still read the

resistance of the resistor).

b. Shorted - indicator swings to zero and stops there -

replace.

c. Open - no reading - replace. (Start capacitor would

read resistor resistance).

2. Testing for ohms between either capacitor terminal and

the capacitor body must show infinite ohms.

Capacitance Check

Using a hookup as shown below, take the amperage and

voltage readings and use them in the formula:

If the value obtained is not within 10% of the rating printed

on the capacitor, replace.
