## Discrepancy

(CAN) DURING A ROUTINE INSPECTION IT WAS DISCOVERED THAT ONE WIRE GOING TO THE OVER VOLTAGE WARNING LIGHT WAS FOUND BURNED.  CAUSE OF THE BURNED WIRE WAS DUE TO FAILURE OF A BUTT SPLICE IN THE WIRE WHICH HAD EXPOSED THE BARE WIRE CAUSING IT TO SHORT OUT. THE BURNED SECTION OF WIRE WAS REPLACED. THE AIRCRAFT WAS GROUND CHECKED SERVICEABLE AND RETURNED TO SERVICE. (TC NR 20070208004)
