TROUBLESHOOTING
2-2. Engine
Check following items before troubleshooting.
• No blown fuses and power is applied up to fuses.
2-2-1. Engine will not start (Starter motor does not run)
• F-R lever must be “N”.
Reference Fig.: 2-2-1
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 value is below standard, battery capacity is insufficient.
C h a r g e o r r e p l a c e
battery.
2. Starter Switch • 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.
Replace starter switch.
3. Starter Motor (1) 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 starter motor does not run even though above items (1)
and (2) are OK, starter motor is faulty.
Replace starter motor.
4. Interlock Switch • When starter switch is ON, measure voltage between
interlock switch terminal 2 and chassis ground.
There is no electricity in normal condition.
• If electricity flows,interlock switch is faulty.
Replace interlock switch.
5. Interlock Relay (1) When starter switch is ON, measure voltage between
interlock relay terminal b and chassis ground.
There is no electricity in normal condition.
(2) When starter switch is START, measure voltage
between interlock relay terminal f and chassis ground.
Standard voltage : 12 V or more
• If above item (1) is OK and item (2) is NG, interlock relay
is faulty.
Replace interlock relay.
6. 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.
