## Discrepancy

(CAN) ACFT WAS IN-FLIGHT FOR ALMOST 3 HRS, WHEN THEY HAD A LT GENERATOR FAILURE.  APU WAS STARTED BUT THEN FAILED.  APU STARTED UP AGAIN BUT HAD REDUCED ELECTRICAL OUTPUT.  A DIVERSION WAS THEN SET UP.  WHILE ENROUTE TO THE CREW THEN HAD A COMPLETE APU AUTO SHUTDOWN, AND THEN DIVERTED TO NEAREST SUITABLE ALTERNATE.  CREW DID DECLARE A PAN PAN MESSAGE WITH ATC, AND AN OVERWEIGHT LANDING WAS CONDUCTED.  REPLACED LT-ENGINE IDG OPS CHECK OK IAW AMM 24-11-01-004-001-0-02 WITH ENGINE IDLE RUN.  REMOVED PN 766088B, SN Y0359.
