Has anyone removed the grounded brush and wired the field winding grounded lead to the case like the Model A? It would have one less brush dragging on the armature and should function the same.
Wouldn't that remove the necessary ground for the armature circuit?
Yes it would need the grounding brush. I didn't think it thru. The brush would still need to be in place and a jumper run from it to the plate just to be sure it was grounded. The ground end could then be run to ether the case or brush. Running the ground wire to the case could make it a little easier to assemble. I forgot the A gens have 3 brushes, the field ground wire goes to the case and the ground brush has a braided wire jumper to the plate.
Ronald, does your diagram represent the normal Model T generator circuit?
Yes, but some explanation is required.
This diagram depicts the electrical (not physical) generator/battery charging circuit in the Model T Ford FA starting and lighting system. It represents the five wires in the charging circuit, but individual wire/connections are not shown. The discharged circuits are not shown for clarity. The diagram was prepared by Bob Cascisa at my request to be part of a detailed explanation of how the circuit works. This article/explanation will appear in September/October Vintage Ford Magazine.
Thank you Ron for the correction. Sometimes we have to think out loud and ask questions to move ahead.
Looks a lot like my diagram prepared over five years ago. But, in all honesty, I seem to recall Ron asking to use it for teaching purposes.
It is indeed.
