TBH I have no idea what it does, how it works, or how to wire it.
I keep messing with it until I stop blowing bulbs. I've put these on 3 different bikes with points, and been happy.

I've had two of these and neither of them regulated correctly with the wiring diagram suggestions listed below. I tried every pin combination humanly possible and none of them functioned as a 12v regulator. Maybe some are internally different than others? Who knows
But good news, your boy Jon has cracked the Da Vinci code. There was a wiring diagram that used to come with these that no longer exists. I was lucky enough to find it on MA.
/====(4) / ====(3) O =====::] \ ====(2) Ground \====(1) Light coil hot lead / lighting wire harness.
Pin 2 gets grounded and then pin 1 is both your stator lighting coil hot lead and the wire that is gonna go to whatever harness you have for your lights. So pin 1 is gonna have 2 wires theoretically. Or maybe 1 wire if your lighting wire harness is already spliced with the stator lighting coil wire.
Sorry if I worded that poorly. It'll make sense once it's in front of you I swear.

It's a regulator that regulates, but doesn't recti

I was only able to get AC out of this thing, produced no DC voltages (verified with both auto-ranging DVM and O-scope).
Borrowing a bit of artwork from a previous post, I tried the following combinations on an AV-7, Le parties CDI, 1/4 throttle. YMMV. All voltages identified below we're measured as positive (+) values.
Configs #1 or 3 are probably what you'd want if you're looking for a regulator. Guessing pin #2 is for battery? Again, YM(and V)MV. NO DC (rectified) output :(
