Hey John - As others have noted you can indeed mess with the regulator and generator and make the system generate 12 volts. However there are a couple additional things you should be aware of: 1 - A 6 volt generator will run hotter when operated on 12 volts. This is because running on 12 volts doubles the current thru the generator field coils. And since heating of the coils varies as the SQUARE of the current (P = I^2 * R for you engineers...), doubling the current causes 4 times as much heat to be developed in the fields. Probably OK if the tractor is used only itnermittantly in cool weather. But if it's run hard in 100 deg ambients, you will increase the risk of frying the generator. 2 - You can tweak the regulator to make 12 volts by increasing the spring tension on the regulator relay. This is the relay whose contacts are help CLOSED by spring tension. (The other relay is the cutout - it's contacts are help OPEN by a spring). It's kinda fussy to set just right, but it can be done. However on a 2-element regulator like the Farmalls use, the voltage regulator relay serves also as a current regulator. So when you mess with the voltage setting you increase the current limit. If your battery shorts a cell or a fault develops in the wiring, the regulator won't limit current to a safe value for the generator, and poof!.....your generator is again fried. Bottom line is you can make your 6 volt generator give 12 volts - just be aware of the risks!

Memories of an IH Super A When I was ? up to 10, I worked on my Papaw's farm in Greeneville, TN every summer. As I grew older (7), it was the thrill of my day to ride or drive on the tractor. My Papaw had a 1954 IH Super A that he bought to replace a Cub. My Papaw raised "baccer" (tobacco) and corn with the Super A, but the fondest memory was of the sawmill. He owned a small sawmill for sawing "baccer" sticks. The Super A was the powerplant. When I was old enough (7 or 8), I would get up early and be dressed to
