What was found
DURING INITIAL CLIMB, THE FIRE ENGINE WARNING BELL FOR NR1 ENGINE SOUNDED BRIEFLY. AT THAT TIME THE CREW PERFORMED AN INSTRUMENT SCAN AND FOUND THE ENGINE INDICATIONS WERE NORMAL. APPROX 10 SECONDS LATER, THE NACELLE TEMP WENT FULL SCALE AND THE FIRE BELL SOUNDED CONTINUOUSLY. THE "B" LOOP INDICATED OVERHEAT/FIRE AND THE "A" LOOP WAS ON DEFERRAL. REPLACED THE "A" LOOP CONNECTOR AND THE ASSOCIATED WIRING DUE TO MECHANICAL DAMAGE; REPAIRED "B" LOOP WIRING IN THE SAME AREA, REF AMM 20-13-15 AND AMM 26-11-02, OPS CHECK NORMAL.
