9 ELECTRICAL SYSTEM
Monitor Lamp (for Charge, Engine Oil Pressure, Pre-heat
and Hazard)
1. After removing the panel board from tractor, remove the
plate behind the panel.
2. Remove the each lamp.
3. Measure the lamp resistance.
4. If it is infinity, replace the lamp with new.
Fuel Level Sensor
1) Lead Terminal Voltage
1. Remove the panel board and disconnect the connector from
the fuel gauge unit after turning the main switch off.
2. Turn the main switch on and measure the voltage with a
voltmeter
across the connector terminal and the chassis.
3. If the voltage differs from the battery voltage, the wiring
harness is faulty.
