Your post has a confusing Statement "when connecting positive ground after negative excessive sparks" The tractor came from the factory with 6v positive if gasoline, 12v if diesel. If you connected the battery backwards (negative ground) and sparks were made at the terminal, you probably welded the points in the cutout relay in the regulator together. This causes the generator to be connected to the battery when stopped. If you put a charger on the battery (now connected correctly) and the fan vibrated, that is what happened with a 90% probability. As John T indicates, disconnect the battery, and charge it while not connected. Tomorrow, or whenever, Disconnect the bat wire and arm/gen wires from the regulator. With an ohm meter, or a continuity tester, test between those two terminals on the regulator. if they are connected, the regulator should be considered fried. If they are open, no conduction, then (with the regulator disconnected) attach the charged battery. The Bat lead to the regulator will now be at battery volts. Touch it to the Bat terminal on the regulator. If no sparks, good. if sparks, the regulator is toast again. If no sparks, touch the Arm lead going to the generator to the Gen/Arm terminal on the regulator. If sparks, regulator is toast again. Replace it. Do as John T indicates to polarize the generator when a new regulator is attached. Jim

Today's Featured Article - The Day Mom Drove the 8N - by Brian Browning. My Dad was wanting to put in a garden but couldn't operate the 8N and handle the old horse drawn plow he had found and rigged up to use with the tractor. Well, he decided to go get Mom out of the house and have her drive the tractor while he walked behind the plow. You got to understand that while my Mom is a hard worker who will always help whenever she can... she had never operated farm machinery before that day. Dad got her out there, explained how the clutch was the same as in our o
