I was looking at somethings on my etrac today, and turned it upside down, I had taken the battery out a little while back, I could hear something clanking around in where the battery goes, and out comes a 1x1 3/8 or so piece of metal with a drilled and taped hole in the center. I live alone and can't see how it could of got in there, has anyone seen this before, I have looked in there and dont see where it could have come loose from, it seems a mystery and is buging me?
