Default Re: 3 brush generator ????

I'd say Bob C is correct. The Fun Projects set up was designed by John Regan who started Fun Projects. The little regulator basically regulates the needed current to the field. As the battery gets closer to fully charged, the current to the field is reduced so the current output is reduced as well. When the system is taxed by turning on the headlamps, more current is required so it puts more into the field. With a "GOOD" battery, the system should charge it back up to a point that all the draw necessary is to keep the ignition system running which is only around 4 or 5 amps which will be shared by the battery. In any case. it shouldn't have to put out any more than 14 to 15 amps which is about the max system capacity anyway. If the thing goes over 15 amps due to a short in the system or the battery, the Fun Projects voltage regular can fry itself. It wouldn't do the generator any good either.
