Instrument Panel, Gauges and Warning Indicators: Description and Operation

The instrument cluster contains the gauges and warning lamps. All gauges have magnetic movements.

When the ignition switch is in the START or RUN position, circuit A21 feeds circuit F14 through a bus bar in the fuse block and fuse 14. Circuit A1 from fuse C in the Power Distribution Center (PDC) supplies voltage to circuit A21. Circuit A21 is HOT at all times.

Circuit F14 provides battery voltage for the warning lamps (except seat belt indicator lamp), transmission up shift lamp, and all gauges.

Circuit E2 from fuse 13 in the fuse block feeds the illumination lamps. Circuit E1 from the headlamp switch powers fuse 13 when the parking lamps or headlamp are ON.

Circuit Z3 provides ground for illumination and indicator lamps. Circuit Z11 provides the ground path for the gauges.
