## Discrepancy

DURING LINE CHECK, MX FOUND THAT THE OVERHEAD EMERGENCY PATHWAY LIGHTING IN THE TAIL COMPARTMENT WAS INOPERATIVE.  MX FOUND A WIRE INSTALLED ON AN INCORRECT TERMINAL AT THE BATTERY PACK.  THE BATTERIES AND THE BATTERY PACK WERE REPLACED AND THE WIRES INSTALLED IAW THE WDM.  THE LIGHTS HAVE RETURNED TO AN OPS CONDITION.
