Alternator for Possible Conversion

[team bogus]

I'm considering buying this alternator for a generator to alternator conversion. It's for a '73-79 beetle or ghia, but what is the three prong connector for? And where is the D+ and ground connection?

Alternators typically have 3 connections: Battery, Warning Light and Ground. It's possible that the 3-prong connector on the alternator you want to buy is for the warning light, ground, and maybe a power exciter connection. (Alternators need power to generate power). Best to get the model number and look up the specs...

Some alternators also require an external regulator. I think that's what you're looking at.

The Bosch AL82X is the standard internally regulated unit and has just two terminals, positive to the battery and the second goes to the light on your dash. Very simple.

That's what I've seen on some other alternators. Two terminals and then a ground. It does look simple.
As for the stand, can I use my stock generator stand or an aftermarket one suited for alternators larger size?

Btw, my car is a '67 Ghia with a '75 1600cc to be installed. Carbureted.

From memory the alternator & generator stands are different, plus if you're running a mechanical fuel pump some of them foul the alternator so that will also need to be changed.

I run a two wire alternator, the wiring to the regulator needs to be altered but its relatively simple.

Thanks guys.
My block was originally for a fuel injected engine, so I'm going to be using an electric fuel pump as there is no provision for a mech. fuel pump. So I won't have that interference issue.
I think I would prefer the internal reg alternator.
