## Discrepancy

PILOT REPORTED AN ALTERNATOR FAILURE.  REMOVED ENGINE COWLING AND FOUND THE POWER WIRE AND THE GROUND WIRE FOR THE ALTERNATOR WERE BROKEN IN HALF ABOUT 3 INCHES FROM THE TERMINALS ON THE ALTERNATOR.  THE ENDS OF BOTH WIRES WERE MELTED, SUSPECTED FROM ARCING.  UPON FURTHER INSPECTION, FOUND THE GROUND WIRE TERMINAL STUD WAS BROKEN OFF THE BACK OF THE ALTERNATOR.  WE SUSPECT THE WIRES BROKE BECAUSE OF THE SHARP BEND RADIUS THE WIRES ARE SUBJECTED TO BETWEEN THE ENGINE BAFFLING AND THE ALTERNATOR.
