Yes, just happened to do mine a few minutes ago. Connect battery and I had my ignition on. Have a short wire and quickly touch the top two connections in the photo. You’ll hear a click and you’re done.

I see that you're already getting contradictory responses between the different places you asked this question.  I can't remember the correct way to polarize ours; however, I can tell you one thing for certain.  There are two typical charging systems out there in the world.  I think they are called A and B.  The contradictory responses you are getting is because each style of charging system requires a different way of polarizing.  Again, I don't remember which style the halftrack has.  I used to know, back when I was searching the internet to learn how to polarize the generator in our truck.  But, I'm getting old and I guess I've replaced that info in my brain with something else.  Just an fyi.

Take a look at this link.  I'm pretty confident we have a "B" circuit since the brushes in a halftracks generator are not insulated.

Yea, Smadge.  Others were telling him the other way on Facebook.  I was just hoping to explain whey there were differences.

Thanks for posting the TM. My Vintage Wiring instruction book says to go to the battery and the armature terminal. I checked my TM and as you have posted, use the field terminal.

I just did it Smadge's way last week.  It worked great and the generator's output increased dramatically and the Ammeter showed much greater charging.  Entire Track runs better too!
