Normal Operation
The ignition switch receives fused battery power from the central junction box (CJB) fuse 103 (30A) circuit 1050 (LG/VT), fuse 116 (30A) circuit 325 (DB/OG) and fuse 110 (30A) circuit 37 (YE). The ignition switch then provides fused battery power to the following circuits based on ignition switch position.
^ OFF-No power on any circuits.
^ RUN-Power on circuits 1040 (RD/BK), 964 (DB/LG), 16 (RD/LG) and 687 (GY/YE).
^ START-Power on circuits 16 (RD/LG) and 1522 (DG).
^ ACC-Power on circuit 964 (DB/LG).
