MG MGB GT V8 Factory Originals Technical - 3.4 Alternator Choices

I need an alternator that mounts to the Camaro two bolt bracket and would prefer one that takes a one wire connection (well, 2 wire really as you need a light circuit to make it charge).

The factory Camaro alternator has a 4 pin plus one bolt wiring connection. The older GM have the 2 wire plus bolt (I don't have the Camaro pigtail in any case, though I suppose I could find it).

Anyone come up with a nice one wire alternator that fits?

1 wire alternators are truly 1 wire. 1 heavy lead to the starter solinoid, no wire to a light circuit. They are self energizing at a particular RPM, around 1200 on mine.

You can probably buy a 1 wire version of popular alternators from Summit or Jegs. A good armature shop- auto electronics that rebuilds starters and alternators- should be able to convert almost ny alternator to 1 wire.

If you take the Camero plug apart & trace the wires, you probably only have 1 main supply & 2 smaller leads, same as the MGB. Some years of the MG's also had multiple wires, but there were duplicates that could be eliminated.

Dan Masters, feel fee to jump in here, I have reached the limits of my knowlege.

Bill,
I wasn't trying to talk in code on the email the other day, we only run one of the four wires in that 4 pin plug for the Camaro 3.4L V6. The OEM wiring harness only uses the one 'excitor' wire as well. Also, if cost of the alternator is an issue, i have a different "Low output" style that can be a little less expensive when purchasing used because they were used on early-mid 1990's Saturns and there were far more of those. This Saturn low output unit only produces 80 amps! There is one modification that needs to be done to install it on the 3.4L bracket, so if you end up looking for the low output, ask me about the small modification needed to fit.

Also, the 1988 and surrounding year units from Camaro, S10 and others are physically much larger and would not fit the bracket if memory serves. I believe the late 1980's styles were the same as the early 1980's style- a good unit, but does not fit most V6/V8 conversions due to size.
