The battery junction box (BJB) receives battery power at all times through circuit 973 (RD). The BJB then provides the ignition switch with fused battery power through fuse 7 (40A) circuit 1050 (VT/LG). The ignition switch has 4 possible states:
^ OFF - No power on any of the circuits.
^ ACC - Power on circuit 297 (BK/LG).
^ RUN - Power on circuits
- 297 (BK/LG)
- 687 (GY/YE)
- 16 (RD/LG)
^ START - Power on circuits
- 32 (RD/LB)
- 16 (RD/LG)
Possible causes
