    We're converting a model A to 12 volt but this time we're using a 12V generator instead of going to an alternator. What is the best way to install a cutout on the generator to prevent overcharging?

    I used the stock Model A generator. I ordered a 12v negative ground cutout from these guys.

    Works great! Be sure to adjust the third brush on the generator to have the right amp output. The cutout comes with instructions on how to do it.
     
  3. I would use a voltage regulator designed for the generator that you are using (what are you going to use?). If you want it to look original (I do) put an original Model A cutout with wires on top of the generator and install the regulator in a hidden location. Trust me, you want to use a voltage regulator and not a cutout.

    We have some GM voltage regulators out of some early Chevy's that came equipped with generators. In this case we're not worried so much about original appearance. I wonder if one of these could be made to work?

    Charlie Stevens is right; Go with a regulator.

    Ford generators are "B" circuit meaning the field is fed with 12 volts to make it charge. GM generators are "A " circuit the field is grounded to make it charge, so a GM regulator won't work you will need to use a Ford regulator. Hope this helps.
