Default 1939-55 Ford 6 Volt Voltage regulator on Modlel A

Back in the day I used a voltage regulator on a Model A generator to eliminate having to adjust the third brush. The regulator was hidden. The third brush was removed and a wire lead from it to to the field (F) terminal on the regulator. The battery (B) terminal was lead to the battery through the normal model A wiring, and the generator (G) terminal was lead to the output terminal on the generator. The voltage regulator not only eliminated the need to adjust the third brush but did a better job of keeping the battery charged. The cutout was built into the regulator. The regulator was adjustable by bending some tabs connected to the springs for the coils.

Who else has done this?

My car came with a voltage regulator when I bought it over 40 years ago. I wouldn’t dream of changing it.

The amperage ratings of the generator regulator have to match the generator, the generator fields have to be wired to match the regulator, some control field power, some ground

Tom's EVR is the best thing we ever did to a Model A Ford. Batteries last crazy long now! Original 6V POS ground, original long generator 1930 Roadster. All stock.
