Check point Check/Cause Action
1. Bulb Check if bulb has burned out or is poorly contacted.
Bulb is faulty or poorly connected.
•
•
Replace bulb.
2. Diode Unit (1) When starter switch is ON and vibration amplitude
selector switch is in “ ” position, measure voltage
between diode unit terminal G and chassis ground.
Standard voltage : 12 V or more
(2) When starter switch is ON and vibration amplitude
selector switch is in “ ” position, measure voltage
between diode unit terminal F and chassis ground.
Standard voltage : 12 V or more
(3) When starter switch is ON, measure voltage between
diode unit terminal A and chassis ground.
Standard voltage : 12 V or more
If above items (1) and (2) are OK and item (3) is NG,
diode unit is faulty.
•
Replace diode unit.
