a newer 12 volt system uses a votage regulator because it has a high current output.
the older 6 volt systems had lower output current generators. some only put out 10 amps maximum. there were two differnt types of "regulators" for the 6 volt syste.
the most basic is the "voltage cutout" which is a small box mounted normally on the generator. the G terminal on the generator gos to the G or a terminal on the cutout, and the other cutout terminal goes to the battery. the F terminal on the generator goes to the light swithc. there is a resistor in the light switch which acts as the "other half of a voltage regulator". the generator puts out 2-3 amps during the day with the light switch off (resistor in the circuit). when you pull out the switch the F terminal is connected straight to ground and the generator runs full out (about 8-10 amps) this works with the lights on. the cutout relay on the generator is adjusting the "voltage" to 6-7 volts at all times.
the second type of "regulator" is an actual voltage-current regulator. it looks like what was used on cars in the early 1960 era. a black box about 3 inches square with three terminals on it (maybe 4). in this setup the resistor which was in the light switch is now in the "regulator" and works automatically to varry the chargning rate. you dont need to turn the light switch on or off. both the G and F terminals on the generator go to the regulator in this setup. the third terminal is B and goes to the battery.
