I don't know maybe its right..?

I re-installed the VR and before starting 12.4 V at the battery

While running 12.0 - to 11.98

I let it run for about 10 minutes to see if it would fall further but it seemed to stay right around 12 V

and when I shut it off ... 12.38 from the battery.

maybe its doing what it's supposed to..but I would have thought I get more that 12 V while running.

I only have 2 fords to compare it to.
