if you need to drive it tomorrow put in the bypass wire like before, your voltages seem good then.
wire it up when you leave for work, when you get there disconnect it, then run it again on your way home and disconnect it when you get there.
so it is your power wire to the vr not the vr that is the problem.
you basically are losing 3 volts at some point, where you have to backtrack the loss to figure out what part or parts are causing the drop.
I have never bothered to fix it when I Get that, I just drop in a relay to give the bypass wire a key on thing so it doesn't leave it energized when the car is off.
it all depends on the time you have to dig, but that is what I do to get rid of the problem.
