Electrical System
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.
a. Back-Up Alarm Removal
1. Disconnect the negative (–) battery cable at the
negative battery terminal (Fig. 9-54, 1).
Figure 9- 54 Battery Cable Connections
2. Label and disconnect the wiring from the back-up
alarm (Fig. 9 -53, 2).
3. Remove the two 1/4-20 nuts and lockwashers
securing the back-up alarm to the vehicle frame.
Remove the alarm from the vehicle.
b. Disassembly
DO NOT disassemble the back-up alarm. Replace a
defective or faulty alarm with a new part.
c. Inspection and Replacement
Inspect the wiring harness connector and alarm terminals
for continuity and shorting. Replace a defective or faulty
alarm with a new part.
d. Installation and Testing
1. Position the back-up alarm (Fig. 9-53, 1) onto the 1/4-20
studs located on the inside frame wall at the rear of
the vehicle. Secure with two lockwashers and 1/4-20
nuts.
2. Connect the wiring harness connector lead
(Fig. 9-53, 2) to the back-up alarm.
3. Connect the negative (–) battery cable to its battery
terminal (Fig. 9-54, 1).
4. Test the alarm by turning the ignition key switch to
the RUN position and shifting the travel select lever
into the REVERSE position. The back-up alarm
should sound.
9.12.3 Instrument Cluster
The information under this heading deals mainly with the
description and function of each indicator in the
operator’s instrument cluster. Appropriate service
procedures for each circuit, as applicable, appear
elsewhere in this section of the manual.
The instrument cluster is of solid-state, printed circuit
design, and contains one
wiring terminal and a display
panel that provides overall monitoring of vehicle functions
and status.
Prevent the instrument cluster from coming into contact
with static or other electrical sources. When washing the
vehicle, keep spray away from the operator’s display
panel. Replace a defective, malfunctioning or faulty panel
with a new unit.
The operator’s display panel provides important
information in a “user friendly” design with easily
recognizable graphic and alpha-numeric indicators. The
panel provides information the operator needs to know
about vehicle and engine functions.
When testing circuits connected to the instrument cluster,
disconnect the harness connector and test the harness
side only.

CAUTION:
Before performing ANY
welding on vehicle, disconnect the negative (–)
battery cable at the negative (–) battery terminal.
Failure to remove the negative (–) battery
cable will result in damage to vehicle electronic
systems.
