Alan,
This is one place the DVM is not a good thing. The voltage stablizer is
actually a bimetalic switch. As it heats up it open, then cools down and
closes. So you actually are turning on and off the flow of current. The
net result is about 10V.
On my Morgan I made and electronic stabalizer - don't really know how well
it works yet. But when I put in the new Temp. guage, it wanted 10V instead
of the 12V. So I took a 3 terminal regulator and set it up to output 10V.
One of these days, I'll check it out and get the car really running. It's
been a show car for the last several years.
