## Discrepancy

DURING A SCHEDULED MX, MX PERSONNEL DISCOVERED THE LAVATORY UPWASH LIGHTS INOPERATIVE.  UPON FURTHER INSPECTION, THE WIRE HARNESS FROM ONE OF THE POWER SUPPLIES WAS FOUND BURNED.  THE BURNED AREA WAS LOCALIZED AND ATTRIBUTED TO ITS PROXIMITY TO THE POWER SUPPLY WHICH TENDS TO REACH VERY HIGH TEMPERATURES.  THE WIRES WERE REPAIRED AND THE HARNESS WAS SECURED AND ROUTED SUCH THAT EXPOSURE TO THE HEAT FROM THE LIGHTING POWER SUPPLY WOULD BE REDUCED.
