Connect the lower negative battery cable (3) to the

negative (-) terminal on the lower battery (5). Swing

the upper battery box (8) in and make sure that the

9.13.2 Front Dash Panel

The information under this heading deals mainly with the

description and function of each indicator in the front

dash panel. Appropriate service procedures for each

circuit, as applicable, appear elsewhere in this section of

the manual.

The front dash panel is of solid-state, printed circuit

design and contains one wiring plug and a display panel

that provides overall monitoring of vehicle functions and

status.

Prevent the panel from coming into contact with static or

other electrical sources. When washing the vehicle, keep

spray away from the front dash panel. Replace a

defective, malfunctioning or faulty panel with a new unit.

The front dash panel provides important information in a

“user friendly” design with easily-recognizable graphic

and alpha-numeric indicators. The panel provides

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.

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.
