I've always followed the JohnT instructions for polarizing generators. Flashing BAT power to ARM post.
I posted this somewhere and started a mini argument, from a guy who always flashed BAT to FIELD. He stated source as the JD electrical manual.
Others have been on one side or the other.
I did more digging, and apparently it depends if you have an A circuit or B circuit generator on how it's flashed.
But I'm wondering if it's even a hard and fast rule....because we both made either choice work on JD generators? I can't remember if JD used A or B type circuits.
Some more info stolen from the internet.....

Depends on the circuit in your generator. According to the Delco-Remy service bulletin dated 7-3-61, there are two different circuit types of generators:
Type A circuit - The field winding is connected to the insulated brush inside the generator and is connected to ground through the contact points in the regulator.
Type B circuit - The field winding is grounded inside the generator and is conncted to the armature circut inside the regulator.
To polarize the generator with: Type A circuit - Momentarily connect a jumper lead between the regulator BATTERY and ARMATURE terminals after all leads have been connected, but before the engine is started.
Type B circuit - Disconnect the lead from the regulator FIELD terminal, and momentarily touch the lead to the regulator BATTERY terminal. This should be done after all other leads have been connected and before the engine is started.

The saga starts with the following message: Hey guys I have a decision to make. I know what you all will probably suggest and it will probably agree with me way down inside, but here it is. I have a picture blown up and framed in my "tractor room" of a Farmall M. It was my Grandpa's tractor, of which whom I never got to meet.
