I have a client with a pond that we put some lights in about 4 years ago. I received a call that one light was not working. We changed all the bulbs back in august. I went out there and put a new bulb in (this is no small task as I have to bring a john boat and row out to the middle) and it still did not work. I traced the wire back and it appears that something had chewed through the wire. Would a turtle chew on the wires? Any ideas??
