Remove the PCB ASS’Y from the electrical component box. Then pull out the fuse from the
PCB ASS’Y
.
Check for continuity by a multimeter as shown below.

6 . Capacitor
Remove the lead wires from the capacitor terminals, and then place a probe on the capacitor
terminals as shown below.
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.
