## Discrepancy

PILOT REPORTED LOSING BOTH ALTERNATORS IN FLIGHT AFTER A MODERATE JOLT OF TURBULENCE, RETURNED WHEN THEY COULD ONLY RESET ONE ALTERNATOR BY FOLLOWING THE QRH PROCEDURE OF REPLACING FIELD FUSES.  INSPECTED & REPAIRED SHORTED F1 WIRE IN RT NACELLE, AS WELL AS REMOVED & INSTALLED THE RT ALTERNATOR & VOLTAGE REGULATOR.  PARALLELED THE SYS.  OPERATIONS CHECKED GOOD AT THIS TIME.
