Fig. 2 Instrument Cluster Without Tachometer:

There are two conventional instrument cluster assemblies available. The clusters incorporate magnetic type gauges and an electronically driven speedometer and odometer.

PURPOSE
The Instrument Cluster, located on the left side of the instrument panel, provides the operator with gauges and warning lamps relating to vehicle operation.

OPERATION
All gauges in the standard and optional cluster have magnetic movements, and are logic-driven.

Magnetic Gauges
All gauges on the clusters are the magnetic type gauges. When the ignition switch is in the OFF position, each gauge should return to its lowest position.

WARNING LAMPS AND INDICATOR LIGHTS
The instrument cluster has warning and indicators lamps for the following systems:
- Low oil pressure
- Charging System
- Brake warning
- Seat belt warning
- Malfunction indicator (check engine) lamp
- Airbag
- High beam indicator
- Right and left turn signals.
- Anti-lock Brakes (ABS) if equipped

CIRCUIT OPERATION
Battery voltage for the cluster's warning lamps and gauges is provided on the G5 circuit through cavity 5 of the right cluster connector. This circuit comes 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.

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. The voltage is provided at cavity 9 of the left cluster connector. Grounding for the cluster is provided on the Z3 circuit and terminates at the instrument panel left center support. Circuit Z3 connects to pin 8 of the right cluster connector.

The F33 circuit also feeds the cluster through a 15 amp fuse in the fuse block cavity 2. This fuse is HOT at all times and is also used to power the headlamp switch. Circuit F33 connects to cavity 6 of the right cluster connector.
