My Model "A" does not have a voltage regulator but a generator cutout.  
The generator has a sliding brush to set the output to your driving 
habits.  Ford suggested a no load output of 8 amps.  But you really need 
to keep an eye on the ammeter to make sure you are charging most of the 
time and not cooking the battery.  If you have it set up for night 
driving, then you have to make sure the engine is not reved up when 
turning on the lights or you'll be driving home without them!
