## Discrepancy

THE FLIGHT CREW FOUND ALL OF THE EEPL CIRCUIT BREAKERS WERE TRIPPED AND WOULD NOT RESET.  THIS PREVENTED THEIR CONTROL THE EMERGENCY PATHWAY LIGHTING IN THE CABIN.  MAINTENANCE REPLACED ONE BATTERY PACK DUE TO BEING WARM TO THE TOUCH, ANOTHER BATTERY PACK DUE TO DISCOLORATION OF THE CIRCUIT BOARD, AND REPAIRED A WIRE WHICH WAS SHORTED TO GROUND.  THE LIGHTS RETURNED TO AN OPERATIONAL CONDITION.
