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.

26.6 volts? I'll bet it cranks! What does that do to a 12 volt battery? I hope that was a typo.

Yep, sure was a typo. Guess I should have done a better job proofreading. Should have been 13.6 volts.

Today's Featured Article - Restoration Story: 1929 McCormick-Deering 10-20 - by Randal Simmon. On July 4th 1998 my dad and I was sitting on the front porch when he said that he was going to sell his two 10-20's to a junk man. He said that the junk man was going to give him $500 for both of them but he hadn't received the money for them yet. So I went into the house and wrote him a check for $500 and bought them myself and said now they are mine. He had bought them about five years before thinking that he was going to restore them himself. After five years sitting in the barn, he changed h ... [Read Article]
