## Discrepancy

IN CRUISE AT FL 370 WITH 7.8 IN CENTER TANK RIGHT CENTER BOOST PUMP LOW PRESS EICAS CAME ON.  THE CTR PMP LOW PRESS INDICATION OCCURED DUE TO LOSS OF PUMP POWER AS A RESULT OF A TRIPPED RT FUEL OVRD CIRCUIT BREAKER (C370).  THE CAUSE OF THE TRIPPED BREAKER WAS TRACED TO AN ELECTRICAL SHORT OF CONNECTOR D40358J.  FURTHER ANALYSIS OF THE CONNECTOR INDICATES THAT THE SHORT CIRCUIT CONDITION WAS A RESULT OF A DAMAGED CONTACT LOCKING MECHANISM WHICH CUT INTO THE CONNECTOR INSULATION & CONTACTED THE ADJACENT WIRE.  REPLACED THE CONNECTOR AND SPLICED IN NEW WIRES PER STANDARD PRACTICES.
