Instrument Panel, Gauges and Warning Indicators: Description and Operation

CIRCUIT OPERATION
The Instrument Cluster, located on the left side of the instrument panel, provides the operator with gauges and warning lamps relating to vehicle operation. All gauges in the standard and optional cluster are magnetic type and logic driven.

Battery voltage for the clusters warning lamps and gauges is provided on the G5 circuit. This circuit connects from the fuse block and is protected by a 5 Amp fuse located in cavity 11. The cluster is powered only when the ignition switch is in the START or RUN position. The cluster is also powered on initial driver's door opening.

Illumination lamps, internal to the cluster, receive battery voltage on the E2 circuit from the 4 Amp fuse located in cavity 12 of the fuse block. This circuit is HOT only when the headlamp switch is in the ON position. Grounding for the cluster is provided on the Z3 circuit and terminates at the instrument panel left center support.

The M1 circuit also feeds the cluster through a 10 Amp fuse in the Power Distribution Center (PDC). This fuse is HOT at all times and also used to power the underhood lamp, and the interior lamps. The fuse is also lifted OPEN during vehicle shipping to reduce battery draw.
