Normal Operation
The instrument cluster receives the START/RUN power from circuit 489 (PK/BK). The RUN/ACC power is from circuit 295 (LB/PK), and the keep-alive power is from circuit 3049 (BK/LG). The instrument cluster grounding is accomplished through circuit 1203 (BK/LB) and the bulb grounding is accomplished through circuit 1205 (BK).

Possible Causes
- circuit 295 (LB/PK) open
- circuit 489 (PK/BK) open
- circuit 1203 (BK/LB) open
- circuit 1205 (BK) open
- circuit 3049 (BK/LG) open
