Indicator Lights

Charge Indicator Light
The charge indicator light should come on when the igni-
tion switch is in the RUN position with the engine not run-
ning. Also, it should illuminate with an improperly
operating charging circuit while the engine is running.
Engine Oil Pressure Light
The engine oil pressure light should come on when the
ignition switch is in the RUN position with the engine not
running. Also, it should illuminate with the engine run-
ning if the engine oil pressure drops to an unsafe level.
IMPORTANT: If the oil pressure indicator light is il-
luminated with the engine running, shut off the en-
gine immediately.
To test the oil pressure light and circuit wiring, ground the
wire attached to oil pressure switch located on the en-
gine near the oil filter. Turn ignition switch to the RUN
position; the engine oil pressure light should come on in-
dicating correct operation of the indicator light and cir-
cuit wiring.
High Temperature Warning Light
If the engine coolant temperature reaches 220
o
(105 C) (approximate), the high temperature warning
light will come on.
NOTE: The PTO will disengage if the engine coolant
temperature reaches 220
To test the high temperature warning light and circuit wir-
ing, turn ignition switch to the RUN position and ground
the wire attached to high temperature warning switch lo-
cated on the engine water pump housing (see High
Temperature Warning Switch in this section). The high
temperature warning light should illuminate.
Glow Plug Indicator Light
The glow plug light should come on when the ignition
switch is placed in the RUN position prior to placing the
ignition switch in START. The light should stay lit for
approximately six (6) seconds while the ignition switch
is left in the RUN position.
Testing Indicator Lights
1. Apply 12 VDC to terminals 1A and 2A (Fig. 24).
2. Ground terminals 1B and 2B (Fig. 24).
3. Both indicator lights should illuminate.
