Check point
1. Battery
2. Starter Switch
3. Starter Motor
4. Starter Relay
Check/Cause
•
Measure battery voltage or specific gravity.
Standard voltage : 12 V or more
Standard gravity : 1.26 or more
•
If value is below standard, battery capacity is insufficient.
•
Check continuity between O-O according to starter switch
connection table.
Switch is OK if there is continuity between connection
O-O.
•
If there is no continuity, starter switch is faulty.
(1) when starter switch is ON, measure voltage between
starter motor terminal B and chassis ground.
Standard voltage : 12 V or more
(2) when starter switch is START, measure voltage
between starter motor terminal S and chassis ground.
Standard voltage : 12 V or more
•
If above items (1) and (2) are OK and starter motor does
not run, starter motor is faulty.
(1) when starter switch is START, measure voltage
between starter relay terminal 86 inlet wire W and
chassis ground.
Standard voltage : 12 V or more
(2) when starter switch is START, measure voltage
between starter relay terminal 30 inlet wire BY and
chassis ground.
Standard voltage : 12 V or more
(3) when starter switch is START, measure voltage
between starter relay terminal 87 outlet wire RW and
chassis ground.
Standard voltage : 12 V or more
•
If above items (1) and (2) are OK and item (3) is NG,
