## Discrepancy

DURING SERVICE CHECK, MAINTENANCE REPORTED L1 AND R1 DOOR EMERGENCY EXIT SIGNS AND FWD SECTION OF EMERGENCY FLOOR PATH LIGHTING INOPERATIVE.  REPLACED POWER SUPPLY UNIT AND BATTERY PACK, WHICH DID NOT CORRECT PROBLEM.  FERRIED AIRCRAFT TO DEN FOR REPAIR.  FOUND CHAFED WIRING UNDER SEAT ROW 5 DEF, WHICH HAD CAUSED THE FUSE TO BLOW AT THE FWD EMERGENCY LIGHT BATTERY CHARGER.  REPAIRED WIRING AND SYSTEM CHECKED OKAY.
