## Discrepancy

DURING TAXI THE ODOR OF BURNED WIRING WAS NOTED BY A CREW MEMBER. DURING FURTHER INVESTIGATION, A WHISP OF SMOKE WAS NOTED IN THE CABIN AREA. TAXI OPERATION WAS ABORTED AT THIS TIME. AIRCRAFT WAS BROUGHT TO MAINTENANCE WHERE IT WAS DISCOVERED THAT THE "+" TERMINAL ON THE LEFT AFT CABIN READING LIGHT HAD BROKEN CAUSING IT TO ARC AGAINST THE LAMP HOUSING. IT SHOULD BE NOTED THAT THERE IS A BLACK RUBBER INSULATING COVER OVER THE "+" AND GROUND TERMINALS THAT MUST BE REMOVED IN ORDER TO VISUALLY CHECK THE CONDITION OF THE TERMINALS AND WIRING CONNECTIONS.
