I just got to setting up my rack, and when I touch certain sections of one of my strips of heat tape, it makes my fingers tingle like they fell asleep. I've never used heat tape before so I don't know if that's normal. But in most situations it normally means I have a short somewhere and that its bad, right? Both sides of my heat tape are taped with aluminum foil tape, with only the middle sticking out. Should I cover the whole section? Or does that mean that I'm going to have to order another section from RBI and wait another week? Ugh, its really disappointing.
