The ammeter shows the amps that the generator is putting out , not the voltage . I use the same ammeter with 12 volts that I use with 6 volts . The original unmodified generator will charge a twelve volt battery with no problem . I use the Fun Projects 12 volt voltage regulator that takes the place of the cut out . As has been said , the generator doesn't know the difference because the generator charges in amps . Generator out put can be controlled by the adjustable brush in the generator . Pushing the adjustable brush downward toward the ground raises the amperage out put . Raising the adjustable brush upward decreases the amperage out put . I have used the 30 amp ammeter when using the 60 amp alternator just for good measure . High amperage out put charges the battery quicker . A voltage regulator , when used prevents overcharging the system .
