Magnet Switch (OC95-E2)
1. Disconnect the connecting lead (1) from the C terminal (2) of
the starter.
2. Connect jumper leads from the negative terminal of 12V
battery to the body and C terminal (2) of the magnet switch.
3. The pinion gear should pop out, when a jumper lead is
connected between the positive terminal of the battery to the
S terminal (3) of the magnet switch.
4. The pinion gear should stay out without the jumper from the
negative terminal to the C terminal (2).
Each test should be carried out for a short time, about 3
to 5 seconds.

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 "GLOW" 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 faulty.

Glow Plug Continuity
1. Disconnect the lead from the glow plugs.
2. Measure the resistance 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.
