Default 3 brush generator ????

I have a few questions that I hope don't seem to ignorant
I have a 39 Standard with a 3 brush generator. It is only putting out about 6.2 V to the battery. I read up and tried adjusting the third brush both directions with virtually no change.

Some have suggested to"Full field" the generator by jumpering the two terminals on the cutout momentarily to see if the output increases.

This got me to wondering if it was hooked up correctly to begin with.

The cutout terminal marked "A" has a multi stranded wire from the generator hooked up to it that I assume is from one of the brushes.

There is a second wire from the generator that is a solid strand and is attached to the base of the cutout.

On the other side of the cutout terminal "B" goes back to the battery.

So the question is which of the two wires should be jumpered to full field the generator.
I've attached a couple of pic's

Thanks in advance
