Easy Checker™
1. Remove the panel board and disconnect the meter panel
connector (1) from it.
2. Turn the main switch on.
3. Measure the voltage with a voltmeter across the terminal (Red /
Yellow) and the earth terminal (Black).
4. If the voltage differs from the battery voltage, the wiring harness
fuses and main switch should be checked.

Engine Oil Pressure Switch
1. Disconnect the lead from the engine oil pressure switch (1) after
turning the main switch OFF.
2. Turn the main switch ON and connect a jumper lead (2) from the
lead to the chassis.
3. If the engine oil pressure indicator lamp does not light, the panel
board circuit or the wiring harness is faulty.

Engine Oil Pressure Switch Continuity
1. Measure the resistance with an ohmmeter across the switch
terminal and the chassis.
2. If 0 Ω is not indicated in the normal state, the switch is faulty.
3. If infinity is not indicated at pressure over 4.9 kPa (0.5 kgf/cm
7 psi), the switch is faulty.

Glow Plug
1. Disconnect the lead from the glow plug (1).
2. Connect the tester positive cable to the glow plug lead and
negative one to the chassis.
3. Measure its voltage with a voltmeter, after turning the main
switch to the preheating or starting position.
4. If its voltage is not approximately the battery one, check the
main switch or wiring harness.
