TROUBLESHOOTING
2-7-5. Hour meter is abnormal
Reference Fig.: 2-7-1
Check point Check/Cause Action
1. Combination Meter (1) When starter switch is ON, measure voltage between
combination meter terminal wires and ground terminal
wire.
Terminal wire R (battery terminal)
and terminal wire B (ground terminal)
Terminal wire P (starter switch terminal)
and terminal wire B (ground terminal)
Standard voltage: 12 V or more
If no abnormality is found, combination meter is faulty. •
Replace combination
meter.
2-7-6. Temperature gauge is abnormal
Reference Fig.: 2-7-1
Check point Check/Cause Action
1. Thermo Unit Disconnect harness and measure resistance of thermo
unit.
Standard resistance:
164.6 Ω [(at unit temperature of 50°C (122°F)]
26.44 Ω [(at unit temperature of 103°C (217°F)]
If resistance is abnormal, thermo unit is faulty.
•
•
Replace thermo unit.
2. Resistor Unit Measure resistance between resistor unit (R4) wire G and
wire Sb.
Standard resistance: 1 Ω
If resistance is abnormal, resistor unit is faulty.
•
•
Replace resistor unit.
3. Combination Meter (1) When starter switch is ON, measure voltage between
combination meter terminal wires and ground terminal
wire.
Terminal wire R (battery terminal)
and terminal wire B (ground terminal)
Terminal wire P (starter switch terminal)
and terminal wire B (ground terminal)
Standard voltage: 12 V or more
If above item is OK and no abnormality is found in thermo
unit and resistor unit, combination meter is faulty.
•
Replace combination
meter.
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.
