Thank You 1931 Flamingo, I didn't think that brush could have that big of an affect.
I moved the adjustable 3rd brush much closer to the output brush and now I do see the amp gauge in the car show charging.

Just to share some of what I learned in case it can help some other newbie.
I did more investigation of the wiring having read a different article about the wires to the cutout being reversed. And wanted to be sure mine is correctly wired.
As I see it there is one brush on the passenger side of the generator. It has a short wire connected to the back of the housing. This is the grounding brush.
I see two brushes on the driver side of the generator, one higher and one lower.
The higher driver side brush is the adjustable 3rd brush. It is connected to one of the wires coming out of the generator.
The lower driver side brush is not adjustable. It is connected to the other wire coming out of the generator. I think this is the output brush.
Note: I had to put insulators between all three brushes and the commutator to check the wiring. Otherwise all brushes are connected through the commutator. Earlier I was trying to lift each brush with my fingers and I don't think that worked very well.

I made sure the wire from the 3rd brush connects to the insulated bolt on back of the cutout. And I made sure the wire from the output brush connects under the screw holding the cutout casing to the generator.

Thanks Again.
