Voltage Stabilizer?

["Christopher M. Delling" <cdelling@ic.net>]

In my continuing effort to get an "accurate" temperature gauge, somone
on the list suggested that my voltage stabilizer may be causing the
problem  I have a 77B.  Should this car have the above referenced part? 
If so, where should I look for it?  What does it look like?  How can I
check it's function.  Any suggestions welcome!
