## Discrepancy

DURING CRUISE ON TRAINING FLIGHT, THE PILOT SIMULATED AN ENG FIRE BY TESTING AMP SIDE OF THE LT FIRE SYS TO ILLUMINATE THE FIRE WARNING T HANDLE.  THE RED LIGHTS ILLUMINATED FOR APPROX ONE SECOND & THEN EXTINGUISHED, DESPITE THE SWITCH STILL BEING DEPRESSED.  AFTER SEVERAL SECONDS BOTH PILOTS NOTICED A ELEC BURNING SMELL, THERE WAS NO VISIBLE SIGN OF SMOKE IN COCKPIT.  THE PILOT OPENED THE CABIN VENTS IAW CHECKLIST INSTRUCTIONS, THE BURNING SMELL DISSIPATED.  THE PILOT DIVERTED BACK & LANDED WITHOUT INCIDENT.  TROUBLESHOOTING REVEALED, CHAFED WIRE ON LT ENG FIRE DETECTION SYS.  REPAIRED CHAFED WIRE & PERFORMED OPERATIONAL CHECK OF FIRE DETECTION SYS.  OPERATIONAL CHECKS WERE NORMAL.
