Check point Check/Cause Action
5. Starter Relay (1) When starter switch is START, measure voltage
between starter relay terminal 1 inlet wire RW and
chassis ground.
Standard voltage : 12 V or more
(2) When starter switch is START, measure voltage
between starter relay terminal 3 inlet wire BW and
chassis ground.
Standard voltage : 12 V or more
(3) When starter switch is START, measure voltage
between starter relay terminal 5 outlet wire W and
chassis ground.
Standard voltage : 12 V or more
If above items (1) and (2) are OK and item (3) is NG,
starter relay is faulty.
•
Replace starter relay.
6. F-R Lever Switch (1) When starter switch is ON, measure voltage between
F-R lever switch terminal COM inlet wire R and chassis
ground.
Standard voltage : 12 V or more
(2) When starter switch is ON, measure voltage between
F-R lever switch terminal NC outlet wire W and chassis
ground.
Standard voltage : 12 V or more
If above item (1) is OK and item (2) is NG, F-R lever
switch is faulty.
•
Replace F-R lever
switch.
7. Interlock Relay (1) When starter switch is ON, measure voltage between
interlock relay terminal 2 inlet wire W and chassis
ground.
Standard voltage : 12 V or more
(2) When starter switch is START, measure voltage
between interlock relay terminal 3 inlet wire Lg and
chassis ground.
Standard voltage : 12 V or more
(3) When starter switch is START, measure voltage
between interlock relay terminal 5 outlet wire BW and
chassis ground.
Standard voltage : 12 V or more
If above items (1) and (2) are OK and item (3) is NG,
interlock relay is faulty.
•
Replace interlock relay.
8. Harness Connecting
Between Terminals
Measure resistance of harness connecting between
terminals.
Standard resistance : 10 Ω or less
If resistance is abnormal, harness is faulty.
•
•
Repair or replace
harness.
