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 with a voltmeter 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 damaged.
