## Discrepancy

AFTER ENGINE START WHEN TURNING OFF THE LEFT OVERRIDE LIGHT SWITCH, THE "MAIN PNL FLOOD LT" CIRCUIT BREAKER TRIPPED OPEN.  SMOKE AND AN ELECTRICAL ODOR WERE OBSERVED IN THE FORWARD-RIGHT SIDE OF THE FLIGHT DECK. THE AIRPLANE WAS REMOVED FROM SERVICE (GROUNDED) AND THE RIGHT INSTRUMENT PANEL FLOOD LIGHT RHEOSTAT WAS FOUND INOPERATIVE. THE CAUSE FOR THE OPEN CIRCUIT BREAKER WAS THE FAULTY RIGHT INSTRUMENT PANEL FLOOD LIGHT RHEOSTAT.
