Kenneth at [email protected] or a knowledgable generator shop can repair or upgrade your generator. It will save doing a butcher job on your tractor along with the time and frustration. We ordered the smaller pulley for my 620's generator and it now charges at idle just like an alternator. Probably will cost the same or less. Coversion to 12V negative ground can be done at the same time. Wonder if you are looking to add more powerful lights or to increase cranking speed and spark energy to compensate for worn components.

Which model of tractor? By 1954 they should be 12 volts from the factory. Are you sure of the year?

I know some of the larger diesels used 12/24 volt systems, but 6V systems were used through the 30 series.

I changed my 430U to 12 volts and was very easy. Starts much better now and easier to find lights. I also just changed over a Farmall Super M. I used a delco alternater with internal regulater. You need to switch the coil wires as the old JDs are positive ground. You can either get a 12 volt coil with internal resister or put a common Chrysler type resister between the switch and coil. Resister is about $3.50 while the coil is around $30. Can give ya more details if ya need them, may depend on the model of tractor. e mail me if you need more
