I just finished the 12 volt conversion on my Case LA. The repair shop replaced the 6 volt fields with 12 volt fields. It is an Auto-Lite generator and the 12 volt fields came from Ace and is part number 145 from them. This generator is the same as used on SC and DC tractors, so this may be of use to some others. The original regulator was used as mounted on the generator and adjusted to 13.6 volts, so installation uses the same wire to the ammater. I replaced the ammeter while I was doing the change. The battery is a group 31 with center posts and replaces the original group 4, 6 volt battery. This tractor has been built up with 4 7/8 sleeves and LP head for about 90 horsepower, so the original 6 volt was not up to the task of starting the engine. Cranks over very good now.
