## Discrepancy

DURING TRANSIT CHECK, THE RIGHT ENGINE FIRE HANDLE LIGHT WAS NOT ILLUMINATED DURING FIRE DETECTION TEST AND LOOP B OF RIGHT ENGINE WITH FAULT.  MAINTENANCE PERSONNEL PERFORMED RIGHT ENGINE FIRE DETECTION TEST IAW AMM 26-10-00, DETECTING LINE OPEN AT MW0326 WIRE AT TERMINAL B2 IAW FIM 26-10 TASK 810 PROCEDURE; SO THE LOOP B OF RIGHT ENGINE WAS DEFERRED IAW MEL 26-2-2 CAT C.  THE ELECTRIC HARNESS OF LOOP B OF RIGHT ENGINE WAS REPLACED IAW AMM 26-11-02, TESTED CORRECT.
