Test in resistance.
TOOL: Multimeter.
Test the resistance of winding. The stepper motor is fault if the resistance of winding
0(short circuit)or
∞（
open circuit
）

1. FUSE
Checking continuity of fuse on PCB ASS’Y.
1) Remove the PCB ASS’Y from the electrical component box..Then pull out the fuse
from the PCB ASS’Y (Fig.1)

2) Check for continuity using a multimeter as shown in Fig.2.

2.CAPACITOR
Remove the lead wires from the capacitor terminals, and then place a probe on the capacitor
terminals as shown in Fig.3.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.
