## Discrepancy

LOST RIGHT INTEGRATED DRIVE GENERATOR AND RECEIVED RIGHT EEC MESSAGE.  RESET RIGHT EEC, BUT IT REMAINED IN ALTERNATE MODE.  *S/D*  REPLACED RIGHT INTEGRATED DRIVE GENERATOR,  GENERATOR CONTROL UNIT AND GENERATOR CONTROL BREAKER.  IDG AND GCU WERE SHOP TESTED AND IN GOOD WORKING CONDITION.  THE FAILURE MOST LIKELY RESULTED IN A GCB MALFUNCTION.
