## Discrepancy

NR 2 ENGINE NO LIGHT OFF AFTER START LEVER RAISED TO IDLE. START ABORTED. IGNITION SWITCH WAS SET TO THE RIGHT IGNITOR.  ACFT GROUNDED.  FOUND NR 2 IGNITER PLUG ARCED. REMOVED AND REPLACED NR 2 ENGINE RIGHT IGNITION EXCITER BOX IAW AMM 74-11-01, AND REMOVED AND REPLACED NR 2 ENGINE RIGHT SIDE IGNITER PLUG IAW AMM 74-21-02. OP'S CHECK GOOD FOR BOTH.
