Hang on a bit, Enrique started out by saying he was trying to get his fuel
gauge fixed:

"Hello List,  I have been trying to revive my Fuel n Temp gauge. I have
tested the green cable that connects to the voltage regulator and I get
solid 12V. The light green/green gives 2 volts and oscillates to about 1.4
and back to 2V..."

He's talking about the instrument voltage stabiliser not the output of
generator or alternator.

Enrique - disconnect the light-green/green from the stabiliser.  If you
still only get about 2v output whilst having 12v input then it definitely is
the stabiliser.
