Jay, You are correct if you order the alternator with the indicator (82101-2
with indicator light), the charging circuit is energized through the light. On
a true 1-wire, there is a voltage bias sensor inside the alternator that
triggers an internal switch to open or close the circuit. On these
Powermasters, the alternator will not "switch on" until the alternator begins
to rotate above a couple hundred RPM and stays on until the engine stops. When
you shut the engine off then that same switch shuts off the circuit so you
don't bleed current and drain the battery. On a 3-wire alternator, the circuit
is triggered by the ignition switch energizing the charging system through the
indicator circuit.
If you don't need a generator light and/or have a voltage gage then get the
1-wire version, simple enough for even us Mechanical Engineers to install!

When doing a one wire installation, keep in mind that the light wire is
critical to the workings of the alternator. It is actually pretty slick or
tricky how it works. It goes to the charging light on the dash. The other
wire to the light goes to keyed 12v, not ground. When the key is turned on,
12v goes through the light, to the coils of the alternator. It charges the
coils and the alternator immediately charges when the engine starts spinning.
Then, 12v goes out of the alternator to the bulb. When the bulb has 12v at
each side, it shuts off.
I learned this the hard way after years of driving an incorrectly wired
alternator, and never understood why the engine had to get over a certain RPM
to start charging.

That would be the PowerMaster 82101 or the 82101-2 with indicator light
terminal. These are one-wire types so you bypass all your regulator harness.
I
go tired of generator bearings burning out (they somehow don't like 7K shift
points) on my 289 HiPo engine and went this way to look stock. The other
advantage is you don't have to kluge brackets onto your car. They are at
Summit Racing, not cheap at $369 and $389 for the indicator model, but you'll
have twice as much juice at idle as the old generator put out at WFO.

Joel
If you are interested in an alternator that closely resembles the Ford OE
generator, there was a discussion on this topic on the CAT Forum last week.
It
is my understanding that they fit into the existing bracket.
Downside...pretty
expensive.
