negative battery terminal (Fig. 10– 44).
Figure 10– 44. Disconnect the negative (-) battery cable
at the negative (-) battery terminal.
2. Label and disconnect the wiring from the back-up
alarm.
3. Two nuts and lockwashers secure the back-up alarm
to weldstuds on the vehicle frame. Remove the nuts
and washers and remove the alarm from the vehicle.
Disassembly
DO NOT disassemble the back-up alarm. Replace a
defective or faulty alarm with a new one.
Inspection and Replacement
Inspect the wiring harness connector and alarm termi-
nals for continuity and shorting. Replace a defective or
faulty alarm with a new one.
Installation and Testing
1. Position the back-up alarm (Fig. 10– 43) on its
mounting studs and secure with two 1/4-20 hex-lock
elastic nuts and 1/4” lockwashers.
2. Connect the wiring harness connector lead to the
back-up alarm.
3. Connect the negative (-) battery cable to its battery
terminal (Fig. 10– 44).
4. Test the alarm by turning the ignition key switch to the
RUN position and shifting the travel select lever into

10.8.2 Operators Display Panel
There are two types of operators display panels in exist-
ence (Fig. 10– 45) at the time this manual was published.
Figure 10– 45. There are two types of
operators display panels.
The information under this heading deals mainly with the
description and function of each indicator in the opera-
tors display panel. Appropriate service procedures for
each circuit, as applicable, appear elsewhere in this sec-
tion of the manual.
The operators display panel is of solid-state, printed cir-
cuit design and contains five wiring terminals or plugs,
two printed-circuit boards mounted piggy-back style with
standoffs, and a display panel that provides overall moni-
toring of vehicle functions and status. Due to the complex
design and solid-state circuitry, the panel is non-service-
able. Electro-static discharge and moisture are two of the
main reasons for malfunction. Prevent the panel from
coming into contact with static or other electrical sources.
When washing the vehicle, keep spray away from the
operators display panel. Replace a defective, malfunc-
tioning or faulty panel with a new unit.
The operators display panel provides important informa-
tion in a “user friendly” design with easily-recognizable
graphic and alpha-numeric indicators. The panel pro-
vides information the operator needs on vehicle and
engine functions.
When testing circuits connected to the dash, disconnect
the harness connector and test the harness side only.
