## Discrepancy

DOOR GIRT BAR C/B TRIPS AFTER DOORS ARMED.  FOUND DOOR ARM LIGHT SOCKET MISALIGNED WITH RECEPTICAL HOLE BEHIND UPPER TRIM PANEL, FORCING LUGS TOGETHER AND SHORTING OUT CAUSING CIRCUIT BREAKER TO POP.  STRAIGHTENED LUGS AND REALIGNED SOCKET, CB STAYS IN, BUT ARM LIGHT STAYS ON, SUSPECT SENSOR BAD (CAUSED BY SHORTED WIRES ON LIGHT ASSY)
