## Discrepancy

DURING MAINTENANCE BASE VISIT FOUND THE OVERWING EMERGENCY LIGHT TO BE INOPERABLE.  THE AIRCRAFT WAS REMOVED FROM SERVICE.   REMOVED AND REPLACED THE NR 4 BATTERY AND CHARGER.  DETERMINED NO FIX AFTER REMOVING AND REPLACING THE NR 4 BATTERY AND BATTERY CHARGER.  REPINNED CONNECTOR P8503 PINS 7 & 9 AND REPLACED THE BATTERY CHARGER.  THE OPERATIONAL CHECK WAS GOOD.  THE AIRCRAFT WAS RETURNED TO SERVICE.
