d. Parking Brake Switch Installation and Testing

in the bezel.

3. If the vehicle has dual batteries, connect both

negative battery cables (10 and 11) to both

batteries.

Connect the lower negative battery cable (10) to the

negative (-) terminal on the lower battery (12). Swing

the upper battery box (15) in and make sure that the

lip (14) on the upper battery box slides below the

any obstructions to vehicle travel.

disengagement, firmly depress the service brake

pedal, disengage the park lock switch, place the

travel select lever in either FORWARD or REVERSE

and in first gear, and slowly press the throttle pedal

while releasing the service brake pedal. The parking

brake should release and the vehicle should travel

freely.

Note: The parking brake indicator (2) on the front dash

panel must illuminate when the parking brake switch is
