Polarizing 48 F1

[CSPIDY]

I’m working on a 1948 F1 Pickup with a V8

Someone had previously switched the battery polarity to neg grid.

I have switched it back to pos grd, verified the coil is pos grd.
when it runs the amp meter moves to discharge

I would like to polarize the generator but not sure what procedure to follow
appears there are two types of generator systems

the wiring is all original, ick

If you have a B circuit, regular will show posts in this order B F A , UNHOOK field wire on reg & touch to battery post on reg, quickly

If A circuit, regular B A F USE A JUMPER from A to B

That’s the question
which type system do I have

Found an old thread where rotorwrench explained it
Pulled the field wire from the generator
touched the field with battery power
Generator works as advertised
Thank you
