COMPONENTS TESTING
Check Fuse and Capacitor
Checking continuity of fuse on PCB ASS’Y.
Remove the PCB ASS’Y from the electrical component box. Then pull out the fuse
from the PCB ASS’Y (Fig.1)

.CAPACITOR
1) Remove the lead wires from the capacitor terminals, and then place a probe on
the capacitor terminals as shown in Fig.3.
2) Observe the deflection of the pointer, setting the resistance measuring range of
the multimeter to the maximum value.
3) The capacitor is “good” if the pointer bounces to a great extent and then gradually
returns to its original position.
4) The range of deflection and deflection time differ according to the capacity of the
capacitor.
