6.1 GLOW PLUG
1. Wiring Lead (Positive)
2 Glow Plug
6.1.1 Lead Terminal Voltage
1. Disconnect the glow plug wiring lead (1) from the glow
plug (2).
2. Connect a voltmeter between the glow plug wiring
lead (1) and a suitable ground on the engine.
3. Energize the glow plug lead and read the voltage.
4. Energize the glow plug lead, engage the starter at the
same time and read the voltage.
5. If the voltage differs from the battery voltage in either
case, the wiring harness or the switch or switches are
faulty.
6.1.2 Glow Plug Continuity
1. Disconnect the glow plug wiring lead (1) from the glow
plug (2).
2. Measure the resistance between the glow plug termi-
nal and the engine body with an ohmmeter.
3. If 0 ohm is indicated, the glow plug may be short--cir-
cuited.
4. If the factory specification is not met the plug is also
faulty.
