Yeah... I started thinking about the connection as well earlier today. At first, I figured that if the connection was bad, all further flexwatt on the parallel further from the power source wouldn't work. But I now know that may not be the case. Considering they're all run in parallell, all the wires may be well connected together, but if only one of the joints isn't soldered correctly, then that single strip wouldn't work well.

I just finished soldering an extra strip of heat tape I have, and I'll try to change out the strip tonight. I hate soldering while they're taped to the rack (worst thing ever btw), so I soldered one on my table. Hopefully after I switch it out with this new one, it should work fine.

I'll keep you guys posted!!!! Thanks for the advice!
