I'm just going to get another power supply. I think that is the problem. At least I hope it is. I got a tester and didn't spend a lot of time trying to figure it out, so I didn't get a reading I think is valid. The tiny power indicator light that is inside the box is not coming on. Like you said, they don't cost that much and just easier. Hopefully that will fix it.

As far as the hot bed, a lot of what I read about that blamed it on the connectors. They are pretty shaky and with the bed being in constant motion, that's where it fails and sometimes burns the connector. One common solution was to solder the connections directly. I'm not comfortable with that since I have never soldered before. I don't want to learn on that. I've gotten really good at attaching the connectors and did switch to larger wire and it's working much better. I just watch it and try to make sure there is as little pressure as possible on the connections.
