Is it still 6 volt Positive ground ? If it's still 6 volt positive ground then it's red to negative black to positive ." It's backwards from a newer type 12 volt system ". You could boil the battery , burn up the instrument gauges, condenser in the distributor, any lights . If you hook the charging cables up wrong . I would change it over to 12 volt neg ground .Cool tractor ! Good luck

Can't beat a Deere. I bought a unstyled model A at auction. It had metal wheels. I found a set of wheels and tires. The guy that had them wanted a tractor like I had. So I doubled my money and sold him the tractor. You are about like me a bunch of projects that move ahead slowly.
Is this an older video you just posted or are you still working on the tractor? If you need a hand, I dont live that far from you. Id be glad to volunteer one afternoon to help you getter started. L emme know.
