Probably a little more to it then that, but I'm sure someone with more info should jump in and give you the correct procedure.

Bob-A is correct. If the generator is in good operating condition No modifications are needed for the generator. Here is how I did mine. Install a twelve volt battery and connect it positive ground and not a single wire will need to be changed. The original coil can be used with a resistor. I prefer A performance 3.0 OHM coil for hotter spark and better pereformance. I use the Pertronix Flame thrower 40.000 volt epoxy filled coil. The Flame thrower coil mounts just like the original and looks pretty much like other replacement coils. I use the original style 20 amp ammeter . An original Cutout, not a repro will work. I prefer the Fun Projects can style voltage regulator. The can style regulator mounts in place of the cutout and looks just like the early cut out and doesn't require any mods to the generator. Other than changing the bulbs you will need a resistor on the horn and electric wiper motor if an electrice wiper is used. The starter works real good on 12 volts. I use the barrel starter drive but the original Bendix drive will work.
I prefer the positive ground twelve volt setup and it has worked great for me. This setup is really easier on the generator because it operates on less amps. If you want to run lots of accessories this may not work as well. I do use the 35 watt halogen bulbs but correct reflectors are necessary if you want the headlamps to focus.
