## Discrepancy

DURING LINE CHECK, MX FOUND THAT THE EMERGENCY PATHWAY LIGHTING IN ROWS 9-14 AND THE LT FWD OVERWING EMERGENCY EXIT SIGN WERE INOPERATIVE.  MX INSTALLED NEW BATTERIES FIRST BUT WHEN THAT DID NOT CORRECT THE PROBLEM THEY REPLACED THE ASSOCIATED FUSE IN THE POWER SUPPLY AND LIGHTS OPERATIONALLY CHECKED GOOD.  (K)
