The "correct police" will tear you up for doing that!! They gave me trouble for converting my 80. My pony motor was shot. Looked like it had be started using sand for oil. Needs 4 sleeves, piston, and rods. Cheaper to buy a new tractor. So, I picked up a used 3 bolt starter from a 855 Cummins (290, 300, 325HP, etc) for basically nothing, put a new solenoid on it for less than $50, it had the correct pinion to mate the flywheel, made the bracket from the scrap pile out of 1/2" material, and put one 12V group 33 battery under the seat. I think that is a 30T starter. Wouldn't swear to it. Stop by your local semi / medium duty repair shop and plunder. They will also fit the stock 820/830 bracket but were made for 900 + cubic inch motors so they spin the JD with full compression with no problem. It has a $50 one wire GM alternator. It will start in 40 degree weather with one battery. The motor is certainly not that worn out either as starting in "cool" weather pretty much proves it is in decent shape. Sure, it won't start when it is 20 degrees outside. I can't think of a good reason to use it in that temp anyway. There is room under the hood for a second battery just above the injector pump cover. I have considered sticking a second battery there with a heat shield between it and the exhaust to eliminate having to help the starter with the compression release when the motor is cold. The tractor is a joy to operate now. While the rest of the "correct" folks are trying to get their pony started and up to speed I am driving away with a mear 5 second push of a button. Yes, for all the correct police I have the complete pony motor all greased up, in a big plastic container, and on a shelf in the shop just in case I win the lottery and decide to fix it for old times sake, or God forbid, sell the tractor. I didn't have a fuel guage so needing 6 volts wasn't a problem. I haven't priced one of those large 6 volt "regulators" in a long time like was made to run old radios, dash lights, and so on. Considering the limited current needed to run a fuel guage about $10 worth of radio shack parts and a few minutes with the soldering gun will give you a 6 volt regulator to handle the fuel guage. If your generator needs attention anyway the price to rebuilt it verses going 12V will be the same. If you have your heart set on a generator, Power Master sells a 12V alternator in an old Delco generator case so it still looks correct. Anything else is just a matter of changing out bulbs that probably need to be changed out anyway.
