So I guess that there's some kind of electrical hiccup in my system. I mean, what else could have made these units just stop working? I'm sending you a PM.........
You know, Baskin, that it all makes sense now. You said they ran, but then shut down until you hooked up the 12v source and then everything ran perfectly. There's no question that the 12v source was no good on my car. The worst part about it is, that I had a mediocre 12v rig, but my mechanic was going to 'fix' that for me when I had it in for a checkup. Uh, yeah.
