Normal Operation
The smart junction box (SJB) fused voltage is supplied by the bussed electrical center (BEC). Circuits 294 (WH/LB), 905 (GY/LB), 1052 (TN/BK), 1523 (DG), and 1679 (WH/YE) supply voltage to the SJB. The SJB is grounded through circuit 1205 (BK).

Possible Causes
- circuit 294 (WH/LB) open or short to ground
- circuit 905 (GY/LB) open or short to ground
- circuit 1052 (TN/BK) open or short to ground
- circuit 1523 (DG) open or short to ground
- circuit 1679 (WH/YE) open or short to ground
