## Discrepancy

WHEN TESTED, THE NR 1 ENGINE FIRE EXTINGUISHER 'T' HANDLE WOULD NOT ILLUMINATE.  MAINTENANCE CLEANED THE ELECTRICAL CONNECTOR BETWEEN THE 'T' HANDLE AND SHAFT, THEN REPLACED THE NR 1 FIRE DETECTION CONTROL MODULE.  SYSTEM WAS CHECKED IAW MM PROCEDURES AND OPS CHECKED GOOD.  AIRCRAFT WAS THEN RELEASED FOR SERVICE.
