Rob,
My all stock temperature-gauge/ voltage-regulator has been remarkably
accurate. I measured the resistance of the sending unit and it's exactly
700 ohms at room temperature. I'll measure it again when it's hot and let
you know this too. My guess is the sending unit is your problem, but you
may need to go through a logical process of elimination to find the real
culprit.
Good luck,
Bob
