Starter Relay
1. Open the panel board and remove the starter relay.
2. Apply battery voltage between terminal 2 and 4, and check for

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.
