ELECTRICAL SYSTEM
(3) Glow Plug
Lead Terminal Voltage
1. Disconnect the 1P connector (1) from the glow plug (2) after
turning the main switch off.
2. Turn the main switch key to the “PREHEAT” position, and
measure the voltage between the lead terminal and the chassis.
3. Make sure that the PTO switch is in the “DISENGAGE” position
and apply the parking brake.
4. Turn the main switch key to the “START” position, and measure
the voltage with a voltmeter between the lead terminal and the
chassis.
5. If the voltage at either position differs from the battery voltage, the
wiring harness or main switch is faulty.

Glow Plug Continuity
1. Disconnect the lead from the glow plugs.
2. Measure the resistance with an ohmmeter between the glow plug
terminal and the chassis.
3. If 0 ohm is indicated, the screw at the tip of the glow plug and the
housing are short-circuited.
4. If the factory specification is not indicated, the glow plug is faulty.
