TROUBLESHOOTING
2-4-5. Starter motor runs even when F-R lever is not at “N” and parking brake is not
applied
Reference Fig.: 2-4-1
Check point Check/Cause Action
1. Forward Switch when starter switch is OFF and F-R lever is “F”, check
continuity between forward switch terminal COM and
terminal NC.
There is no continuity in normal condition.
If there is continuity, forward switch is faulty.
•
•
Replace forward switch.
2. Reverse Switch when starter switch is OFF and F-R lever is “R”, check
continuity between reverse switch terminal COM and
terminal NC.
There is no continuity in normal condition.
If there is continuity, reverse switch is faulty.
•
•
Replace reverse switch.
3. Parking Brake Switch when starter switch is OFF and parking brake switch is
released position, check continuity between parking brake
switch terminal 1 and 2.
There is no continuity in normal condition.
If there is continuity, parking brake switch is faulty.
•
•
Replace parking brake
switch.
2-4-6. Engine speed cannot be switched
Reference Fig. : 2-4-1
Check point Check/Cause Action
1. Throttle Switch (1) when throttle switch is “IDLE”, check continuity between
throttle switch terminals 1 and 2, 4 and 6.
There is continuity in normal condition.
(2) when throttle switch is “MID”, check continuity between
throttle switch terminals 1 and 3, 4 and 6.
There is continuity in normal condition.
(3) when throttle switch is “FULL”, check continuity
between throttle switch terminals 1 and 3, 4 and 5.
There is continuity in normal condition.
If above item (1), (2) or (3) is NG, throttle switch is faulty. •
Replace throttle switch.
2. Throttle Stop Relay (1) when starter switch is ON, measure voltage between
throttle stop relay terminal 1 inlet wire G and terminal 2
outlet wire GW.
There is no electricity in normal condition.
(2) when starter switch is ON, check continuity between
throttle stop relay terminal 3 and terminal 4
There is continuity in normal condition.
If above item (1) is OK and item (2) is NG, throttle stop
relay is faulty.
•
Replace throttle stop
relay.
3. 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.
