## Discrepancy

WITH LEFT IGNITION SYSTEM IN OVERRIDE, THE LEFT ENGINE DID NOT START.  THE CIRCUIT BREAKER C/B U42 WAS REESTABLISHED BUT FAILURE CONTINUED.  THE LEFT IGNITION C/B WAS DEFERRED IAW MEL 74-A BUT DURING PUSH BACK, THE LEFT ENGINE IGNITION WAS OUT SERVICE AGAIN.  THE LEFT SIDE EXCITER IGNITION WAS REPLACED IAW MM 74-10-01, TESTED CORRECT.  DURING OVERNIGHT SERVICE, IGNITION SYSTEM WAS TESTED IAW MM 74-10-01, ALL CORRECT.
