I have run my restored 1933 roadster on 12 volt for over 40 years.
same original coil - starter & generator. the generator will charge (just adjust 3rd brush to wanted amp charge ) I use an additional ( common 12 volt ign resistor ) for ign
change bulbs to 12 volt . horns work better . switch wires on am meter . I use a small 12 volt battery in a battery box I make ( also sell ) that makes the battery look like a 33 battery. My lights are brighter --- my car starts faster all in all best of both worlds.
