Mike,
I'm certainly not an electrical whiz, but according to this article, the
difference between a 3 wire and 1 wire is a different internal voltage
regulator in the one wire.

For more on voltage sensing (which a one wire alternator doesn't have), see
this article.

And anyone with an amp meter, for safety reasons should convert to a volt
meter. http://www.madelectrical.com/electricaltech/amp-gauges.shtml

Hey Bill Taylor and other electrically smart people,
Johnny Woods asked me to ask a question on his behalf. He's installing a
Powermaster 100-amp alternator on his car; he bought a one-wire model but
now wants to convert it to three-wire operation. He talked to the
Powermaster tech line and they told him it wasn't possible, which I find
difficult to
believe.
At the same time, they told him that the factory wiring wasn't up to the
task of handling 100 amps, and advised him that he should run TWO power
wires
from the alternator; the second should run from the alternator output
directly to the battery cable on the starter solenoid (and thence back to
the
battery).
Their premise is that by doing so, a percentage of the alternator's output
would run through the ammeter, to the battery, while the rest would bypass
the ammeter.
This sounds totally hokey to me, and completely unnecessary. What say
you, electrically smart people?
Please, please hit 'reply all' so your replies will be seen by Johnny, who
is on the PI forum but not this one.
Thanks!
Mike
