I have a small, compact Nippon Denso alternator here in working order (series 5685) that came from an early 90's Jeep. I was thinking it's maybe a candidate for a 12V conversion on a 1940's 6V tractor. I know most conversions favor certain GM one-wire alternators, this smaller one I have would be my preference for size alone. So first, I guess one would call it a 3-wire alternator right? I am also assuming (hoping) it has a built in regulator of some kind for charge control. See the picture below of the one I have here.
The one big heavy terminal tagged B would obviously be the one from the battery's positive post, the three locations that are red-tagged aren't really wiring terminals, they hold the end cover on & go to ground. But one has a threaded terminal immediately next to it where a wire could be grounded if needed.
My question relates to the two nut-type terminals that are marked 1 & 2 in the picture. Neither one is stamped with a number or a letter of any kind next to it on the alternator.
Is this a candidate for a simple 12V conversion? Any advice or help is appreciated along with a diagram if someone has one they could post.

Today's Featured Article - Tractor Hydraulics - The Basics - by Curtis Von Fange. Hydraulics was one of the greatest inventions for helping man compound the work he can do. It’s amazing how a little floor jack can lift tons and tons of weight with just the flick of a handle. What’s even more amazing is that all the principals of hydraulic theory can be wrapped up in such a small package. This same package applies to any hydraulic system from the largest bulldozer to the oldest and smallest tractor. This short series will take a look at the basic layout of a simple hydraul
