## Discrepancy

CAN)PILOTS REPORTED FIRE WARNING ACTIVATED & LASTED ABOUT 20 SECONDS THEN DEACT IVATED.  NORMAL LANDING WAS CARRIED OUT BUT SYSTEM ACTIVATED AGAIN ON TAXIING & REMAINED ON.  MAINTENANCE TROUBLE SHOT THE FAULT TO THE FIREWALL CONNECTION BEHIND THE INERTIAL SEPARATOR & THE UPPER STANBY SIDE OF THE FIREWALL.  CONNECTIONS WERE CLEANED & DRIED & REINSTALLED.  APPROXIMATELY 2.5 HOURS INTO SERVICE THE FAULT REAPPEARED.  AIRCRAFT GROUNDED FOR FURTHER INVESTIGATION.  INVESTIGATION REVEALED THAT BOTH ENDS OF THE FIRE WIRE, ON THE INERTIAL SEPARATOR & ONE UPPER STANDBY SIDE FIREWALL WERE LOOSE CAUSING AN INTERMITTENT CIRCUIT.  THE FIRE WIRE WAS REPLACED & NO FURTHER FAULTS WERE OCCURRED.
