Your 6 amp charge rate is adequate for a car that has a battery minder connected up to it while it is parked in a garage between uses. Then you are always going out with a fully charged battery. You can run at night for a few hours without killing the battery if you need to.

This PITA of adjusting the 3rd brush is why so many people install a hidden voltage regulator on the original generators. Then you get the current you need when you need it but less at other times, after the battery is charged.

As many of you know, I am not a big proponent of "modern upgrades" on the Model A because they often create more problems than they cure. To me, the voltage regulator is one exception. They really do help keep your battery charged without boiling the water out of it. They get you more current for lights when you need it. Worth installing.

Where would I get a voltage regulator??
