## Discrepancy

DURING CLIMB HAD 2 VERY BRIEF (1-2 SECOND) INTERMITTENT APU FIRE WARNINGS (EICAS MESSAGE AND MASTER LIGHT/BELL).  AFTER CONSULTING WITH DISPATCH, MC AND FLEET TRAINING CAPTAIN APU FIRE HANDLE WAS PULLED BUT NOT TURNED.  APU HAD BEEN SHUT DOWN NORMALLY PRIOR TO TAXI AND WAS NOT OPERATIONAL AT THE TIME OF BRIEF FIRE INDICATIONS. MAINTENANCE REPLACED A TERMINAL LUG AND APU FIRE AFLOT CARD.  OPERATIONAL CHECKED GOOD AND AIRCRAFT WAS RETURNED TO SERVICE.
