Glow Plug Lead Terminal Voltage
1. Disconnect the wiring lead (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. Turn the main switch key to the "START" position, and measure
the voltage between the lead terminal and the chassis.
4. If the voltage at either position differs from the battery voltage,
the wiring harness or main switch is faulty.
