9-2. Checking Motor Capacitor
Remove the lead wires from the capacitor terminals, and
then place a probe on the capacitor terminals as shown
in Fig. 5. Observe the deflection of the pointer, setting
the resistance measuring range of the multimeter to the
maximum value.
The capacitor is “good” if the pointer bounces to a great
extent and then gradually returns to its original position.
The range of deflection and deflection time differ
according to the capacity of the capacitor.
