## Discrepancy

5 OUT OF 6 FORWARD LOWER CARGO DOOR SILL AREA LIGHTS DO NOT ILLUMINATE DURING CARGO LOADING OPERATIONS.  AT THE FORWARD UPPER SILL LIGHT POSITION, SMOKE WAS FOUND AT A BURNED WIRE. THE FORWARD UPPER LIGHT ASSEMBLY WAS REMOVED AND FOUND 4 WIRES BURNED, 2 SHORTED TOGETHER, AND 2 TERMINAL ENDS WERE BURNED OFF.  ALSO, FOUND CIRCUIT BREAKER C21, TERMINAL 2 BURNED.  THE CORRECTIVE ACTION ACCOMPLISHED WAS REMOVING & REPAIRING THE BURNED WIRING, REPLACING THE TERMINALS, AND REPLACING THE FORWARD CARGO COMPARTMENT LIGHTS TRANSFORMER T148. THE SUSPECTED CAUSE OF THE INOPERATIVE LIGHTS AND BURNED WIRING IS A FAULTY TRANSFORMER T148.
