John, thanks for the reply. I try to exhaust the search function as much as possible, before posting, but I couldn't quite find what I was looking for. I'm away for a few days, but will post with my results when I return home.

One question, am I correct in assuming with the ignition on, there should not be any voltage at the D+ at the gauge? How about voltage from the alternator D+ to the D+ input on the VR?

Thanks, Ryan
