## Discrepancy

THE AIRCRAFT WAS FLYING THROUGH IMC, WITH ALOT OF RAIN ON THEIR WAY TO DESTINATION.  AS THE CREW WAS LETTING DOWN TO LAND THE LT ENGINE FIRE LIGHT LIT UP.  THE CREW SCANNED ALL THE GAGES, AND DETERMINED THAT THIS WAS A FALSE LIGHT.  THE AC LANDED WITHOUT COMPLICATION.  UPON INSPECTION OF THE LT ENGINE FIRE DETECT SYSTEM, THE TECH FOUND SOME VERY LIGHT CORROSION AND MOISTURE ON THE J102 CONNECTOR PLUG, LOCATED ON THE LT ENGINE FIRE WALL.  THE MOISTURE AND CORROSION WAS REMOVED AND THE FIRE DETECT SYSTEM TESTED PROPERLY, THE AC WAS RETURNED TO SERVICE.  APPLING A THIN COATING OF DC-4 GREASE IN THE CONNECTOR PLUG WOULD PREVENT MOISTURE FROM ENTERING THE PLUG AND THEREFORE KEEP THE CORROSION OUT.  (K)
