The '32 V8 used a resister and I assume the vehicle the 59a came out of did also. That tells me to use a resister. The Model B did not use a resister but that is a different electrical system. It is my understanding that omitting the resister will burn out the coil.

Another topic. If you have a generator that puts out more than 20 amps I would recommend adding a shunt across the ammeter to take some of the amperage (see photo).
