Check point Check/Cause Action
1. Battery Measure battery voltage or specific gravity.
Standard voltage : 12 V or more
Standard gravity : 1.26 or more
If measured value is below standard, battery capacity is
insufficient.
•
•
Charge or replace
battery.
2. Starter Switch Check continuity between Ο – Ο according to starter
switch connection table.
Switch is OK if there is continuity between connection
Ο – Ο.
If there is no continuity, starter switch is faulty.
•
•
Replace starter switch.
3. Starter Motor (1) When starter switch is START, measure voltage
between starter motor terminal 30 and chassis ground.
Standard voltage: 12 V or more
(2) When starter switch is START, measure voltage
between starter motor terminal 50 and chassis ground.
Standard voltage: 12 V or more
If starter motor does not run even though above items (1)
and (2) are OK, starter motor is faulty.
•
Replace starter motor.
4. Battery Relay (1) When starter switch is OFF, measure voltage between
battery relay primary terminal COM and chassis ground.
Standard voltage: 12 V or more
(2) When starter switch is ON, measure voltage between
battery relay coil terminal BR inlet wire BrY and coil
ground terminal E.
Standard voltage: 12 V or more
(3) When starter switch is ON, measure voltage between
battery relay secondary terminal NO and chassis
ground.
Standard voltage: 12 V or more
If above items (1) and (2) are OK and item (3) is NG,
