Today I decided to troubleshoot my inop pool light. We just bought the home a few weeks ago and the previous owner said it was working recently, but now it trips the breaker when energized. I didn't find anything obvious, but I did find this old, nasty looking piece of cloth behind the light. It pretty much disintegrated when touched. I went ahead and removed what I could and vacuumed to waste the rest. Between me and the nautilus pro we seem to have gotten most all of it. Any ideas what that was doing in there? It wasn't attached to anything as best I can tell. I just had a leak detection company do a full leak check a couple days ago and the light housing wasn't leaking, so that's something good at least. Hopefully replacing the light doesn't change that. Thanks!
