## Discrepancy

WHILE WORKING AMDS W/C 3351-7008, FOUND ROWS 4,5,6 AISLE LIGHTS AND BOTH O/W EXIT EMERGENCY LIGHTS DID NOT PASS CAP CHECK.  R & R BATTERY PACKS AT ROWS 4,5,6; LEFT O/W EXIT DOOR AND RIGHT O/W EXIT DOOR, AS WELL AS LEFT O/W EXIT DOOR POWER SUPPLY. PER B757 AMM 33-51. BATTERY PACKS WERE FOR M730, M11487, AND M11384. POWER SUPPLY AT M11487. ALSO REPLACED BATTERY PACK AT M11613. OPS CK GOOD.
