TROUBLESHOOTING
2-4-3. No charging
Reference Fig.: 2-4-1
Check point Check/Cause Action
1. Alternator After starting engine, measure voltage between alternator
terminal BATTERY wire R and chassis ground.
Standard voltage: At least intermediate engine speed,
14 V or more
If voltage is lower than standard, alternator is faulty.
If voltage is higher than standard, regulator is faulty.
If voltage is normal and battery is not charged, battery is
faulty.

Replace alternator.
Replace regulator.
Replace battery.
2-4-4. Engine speed cannot be switched
Reference Fig. : 2-4-1
Check point Check/Cause Action
1. Throttle Switch
(1) When throttle switch is in “IDLE” position, check
continuity between throttle switch terminals 1 and 2, 4
and 6.
There is continuity in normal condition.
(2) When throttle switch is in “MID” position, check
continuity between throttle switch terminals 1 and 3, 4
and 6.
There is continuity in normal condition.
(3) When throttle switch is in “FULL” position, 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 Relay
(1) When starter switch is ON and throttle switch is in
“FULL” position, measure voltage between throttle relay
terminal a inlet wire RW and chassis ground.
Standard voltage : 12 V or more
(2) When starter switch is ON and throttle switch is in
“FULL” position, measure voltage between throttle relay
terminal e outlet wire WB and chassis ground.
There is electricity in normal condition.
(3) When starter switch is ON and throttle switch is in “IDLE”
or “MID” position, measure voltage between throttle
relay terminal f outlet wire LB and chassis ground.
There is electricity in normal condition.
If above item (1) is OK and item (2) or (3) is NG, throttle
relay is faulty.
•
Replace throttle 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.
