Indicator Lights
Engine Oil Pressure Light
The oil pressure light should come on when the ignition
switch is in the ON position with the engine not running.
Also, it should light with the engine running if the engine
oil pressure drops below 4.3 PSI (0.3 kg/cm
2 ).
To test the oil pressure light and circuit wiring, ground the
gray wire attached to oil pressure switch located on the
front side of engine near the oil dipstick. Turn ignition
switch to the ON position; the oil pressure light should
come on indicating correct operation of the electrical
wiring to the oil pressure switch.

To test the high temperature shutdown light and circuit
wiring, start the engine and ground the blue/white wire
attached to high temperature shutdown switch located
on water pump housing (see High Temperature Shut-
down Switch in this Chapter). Warning light should illu-
minate and engine should stop running.
Glow Plug Indicator Light
The glow plug light should come on when the ignition
switch is placed in the ON position prior to placing the
ignition switch in START. The light should stay lit for
approximately 5 seconds while the ignition switch is left
in the ON position.

tion switch is in the ON position with the engine not run-
ning, or with an improperly operating charging circuit
