Test D: No Power In START

Normal Operation
The battery Junction box (BJB) receives fused battery power through fusible link A (12 gauge, YE) and fusible link B (12 gauge, YE) along circuit 37 (YE). The BJB then provides the ignition switch with fused battery power through fuse 7 (60A) along circuit 1050 (LG/VT). When placed in RUN, the ignition switch provides fused battery power to the central Junction box (CJB) through circuits 687 (GY/YE), 297 (BK/LG) and 1499 (PK/LG).

Possible Causes
^ An open in circuit(s):
- 1499 (PK/LG)
