Electrical System
e. Hydraulic Oil Temperature Warning Indicator
This warning light (6) will activate when the
hydraulic oil temperature is above 195° F (91°
C). The vehicle should be stopped and the
engine allowed to idle at high idle for five
minutes.
If the light continues to illuminate after five minutes, the
engine must be shut down to help avoid damage in the
hydraulic system. For additional information refer to
Section 9.8.33, “Hydraulic Oil Temperature Warning
Indicator Troubleshooting.”
f. Alternator Charging Warning Indicator
This light (7) illuminates when the charging
system is not working properly. Check and
service the alternator and battery as required.
For additional information refer to Section
9.7.38, “Charging Circuit and Troubleshooting.”
g. Engine Oil Pressure Warning Indicator
This indicator (8) illuminates and an audible
alarm sounds after 15 seconds if the engine is
not started; this is normal. When the ignition key
switch is turned to the OFF position, the
indicator is reset.
Should the light and alarm begin during engine operation,
the engine oil pressure is too low. The engine must be
shut down as soon as practical to help avoid engine
damage. For additional information refer to Section
9.8.35, “Engine Oil Pressure Warning Indicator
Troubleshooting.”
9.11.2 Back-up Alarm
The back-up alarm (9) is located at the rear of the vehicle.
When the transmission shift control switch (travel select
lever) is shifted to the (R) REVERSE position, the back-
up alarm will automatically sound.
Place the travel select lever in (R) REVERSE to test the
back-up alarm. The back-up alarm must not sound when
the travel select lever is in (N) NEUTRAL or (F)
FORWARD. Also, with the ignition key switch in the RUN
position, the back-up alarm will sound when the travel
select lever is shifted into the (R) REVERSE position.
The back-up alarm is energized via current from the
transmission shift control switch, part of the travel select
lever, mounted within the steering column. See the
appropriate wiring schematic and diagram in this section
to help understand the back-up alarm circuit. Refer to
Section 4.3.2, c. “Transmission Travel and Gear Select
Lever Removal,” for information on removing and
replacing the transmission shift control switch.

2. Label and disconnect the wiring from the back-up
alarm (10).
3. Remove the two 1/4-20 nuts and lockwashers
