## Discrepancy

AN ELECTRICAL ODOR WAS MOMENTARILY OBSERVED IN THE FORWARD GALLEY WHILE IN FLIGHT.  UPON INVESTIGATION THE RIGHT DC TRANSFER RELAY WAS FOUND TRIPPED AND THE RIGHT DC LOAD METER READ ZERO.  THE TRANSFER CIRCUIT BREAKER WAS NOT RESET AND THE ODOR WENT AWAY.  THE AIRCRAFT LANDED AT EWR WITHOUT FURTHER PROBLEM.  MAINTENANCE FOUND THE RIGHT NR 1 TRANSFORMER RECTIFIER AT FAULT.  THE TRANSFORMER RECTIFIER WAS REMOVED AND REPLACED.
