Test D: No Power in START

Test D: No Power In START

Normal Operation
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). When placed in START, the ignition switch provides voltage to smart junction box (SJB) fuses 21 (15A) and 34 (5A) through circuit 32 (RD/LB) and to SJB fuses 16 (10A), 20 (10A) and 32 (10A) through circuit 16 (RD/LG).

Possible causes
^ Fuse
^ An open in circuit(s):
- 32 (RD/LB)
- 16 (RD/LG)
^ Ignition switch
