I had an OEM alternator on my heap that had the stand apart voltage reg. i replaced the alt with a CS130 that is internally regulated. I looked up all the info on the WWW There is a ton out there. Basically you need a charge wire to your battery, a voltage sensing wire from the battery and a field exciter wire to the alt. There are some one wire alts out there, but I prefer the 3 wire as I personally think it just works better. Google is your friend

An internally regulated alternator will not need a voltage regulator. An externally regulated alternator will need the voltage regulator that is specific to it's model.

Here are a couple of examples of simple alternator wiring.

Make sure you've got a 12V system, and not a 6V. Both were common in the early 1960s.

If you have a 6V, you'll have to change more than just the generator - battery, ignition coil, and possibly a few other components as well. Still, it shouldn't be too bad.
