CIRCUIT OPERATION
Instrument Cluster
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 12. Circuit A1 from fuse 3 in the Power Distribution Center (PDC) supplies voltage to circuit A21.

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 headlamps are ON.

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