Thanks Howard, I went for a drive just now, and actually am happy with the numbers I measured. The first few minutes of driving at speed, I was getting 7.3 to 7.4, and after about 15-20 min of driving I was getting about 7.1 to 7.2. I have the gauge pulling a voltage from the back of the ignition switch, so there might be a 1/10 of a volt or so getting lost along the way.
I guess the best place to hook this gauge would be to a ground in the engine bay, and the bat terminal on the voltage regulator....That would give me the most accurate reading so I can really be sure if the 7.4 is being maintained. I may optimize the wiring and take some more measurements, but the voltage is in the right ball park.
