If I'm reading this response correctly, it appears something is wrong with the original roboRIO's bus. First off, double check for debris. Then, see if you have continuity between the positive and negative terminals on the bus using your multimeter. The voltage you're getting at each port is really low compared to what you should be getting, so if it is a problem with the RIO (which is what I suspect), it's at the connector. Make absolutely sure there's nothing wrong there before you go troubleshooting anything else.

I'll also second kgzak's statement about using the correct PDP. Using the old one can really mess up a RIO.
