Perhaps I'm confused, Frank.  A standard 7127 (aka 10Si) is called a "3
wire" alternator, it has two smaller tabs for control signals and a big post
for the output.  It is only grounded through the case (although there is
usually a spare post where a ground cable can be attached if you wish).
Looking at the back of the alternator), the left-hand tab is #1, which is
the
output to the warning light on the dash.  The right-hand tab should be
#2, the
'sense' input, which needs to see battery voltage.  Optimum setup
IMO is to
run a separate wire from the starter solenoid to this terminal,
but you can
just jumper it to the output post if you want.

I've attached a scan from a GM
manual with a diagram.  As usual, if anyone
else wants a copy, email me
offlist.
