TROUBLESHOOTING
2-3. Propulsion
Check following items before troubleshooting.
• No blown fuses and power is applied up to fuses.
2-3-1. Hour meter is abnormal
Reference Fig.: 2-2-1
Check point Check/Cause Action
1. Hour meter (1) When starter switch is ON, measure voltage between
hour meter wire R and chassis ground.
Standard voltage : 12 V or more
(2) Check that hour meter wire E is reliably grounded.
• If items (1) and (2) are OK and hour meter does not work,
hour meter is faulty.
Replace hour meter.
2-3-2. Horn does not sound
Reference Fig. : 2-2-1
Check point Check/Cause Action
1. Horn • Disconnect horn and directly connect battery positive
terminal to horn terminal wire marked
HORN
and
negative terminal to horn terminal wire E side.
• If horn does not sound, horn is faulty.
Replace horn.
2. Horn Relay (1) When starter switch is ON and horn switch is pressed,
measure voltage between horn relay terminal 2 and
chassis ground.
Standard voltage : 12 V or more
(2) When starter switch is ON and horn switch is pressed,
measure voltage between horn relay terminal 5 and
chassis ground.
Standard voltage : 12 V or more
• If above item (1) is OK and item (2) is NG, horn relay is
faulty.
Replace horn relay.
3. Horn Switch • When horn switch is OFF, measure resistance between
horn switch terminals.
Standard resistance : 100 kΩ or more
• If resistance is abnormal, horn switch is faulty.
Replace horn switch.
4. 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.
