You should keep all this in the other thread where you started asking questions, I think.

If that was a DC wall wart (not AC) I think you've got a problem. Something in the power supply section is reversed or shorted out. (I don't think it would smoke if you just reversed the wall wart polarity.) I saw the pictures you posted but they weren't clear enough or close enough to really figure out exactly what's going on.
