I have a turbo twist 12x that has been sitting in a box for over a yr and i thought about hooking it up. It turns on and the bulb lights but you can notice a faint burning smell while lit. I took it apart to inspect for any char marks but cannot find anything. Anyone have any ideas on how to check this thing over to see if it is not a shock hazard when i run water through it?
