b.
Test
(1) Tag and disconnect wire leads on capacitor (C2) .
(2) Using a capacitance tester, check capacitance across terminals.
(3) If capacitance does not read 25.00 ±2.5 microfarads, the capacitor is
faulty and must be replaced.
(4) If a capacitance tester is not available, conduct the following test
using a multimeter:
Set meter to highest OHMS scale.
Connect positive (+) meter lead to positive (+) capacitor terminal.
l Connect negative (-) meter lead to negative (-) capacitor terminal.
Engage meter.
(5) A good capacitor will be shown by meter quickly registering high
resistance, then slowly backing off to zero resistance.
(6) If meter displays high resistance and remains there, the capacitor is
internally shorted and must be replaced.
(7) If the meter does not show any resistance, the capacitor is open and
must be replaced.
