Default Re: Generator Brush Adjustment

Yes , The slip ring will rotate only so far . If a voltage regulator is used it will allow the generator to cycle between higher and lower charge rate to prevent overcharging the battery . When a voltage regulator isn't used , the adjustable brush needs to be set for a lower charge rate because the generator will charge the same rate most of the time without cycling .

I use the Fun Projects voltage regulator that takes the place of the cutout . I set the third brush for a ten amp maximum charge . In normal operation the generator would only charge a short time on ten amps . Ten amps would quickly charge the battery . Higher amps will only be needed when the lights are used . The ammeter will mostly show a discharge when the lights are on . It takes a good while to kill the battery so not to worry too much .
