I have a farmall super A that I bought last week, tractor was running except the altinator wasn't working, two days ago I went to start it with the battery fully charged it turned over twice and then nothing. I got my test light out and I am getting power to the starter, and then I noticed the 12 to 6 volt ballast rister is smoking and the coil is hot. So I decided to rewire the entire tractor because it needed it wires were original and in bad shape plus I put a new built in resister coil on it,and wired the alternator up because the previous owner didn't have it wire right all. I used 10ga wire which is over kill but I wanted it to be right. Now I have power to the starter still and power and the lights switch but the tractor still won't turn over and the new coil is still getting hot. Please help if you know what it might be. I'm sure I wired it right I have check the wire chart over and over and I am getting power in all the right places. Thanks!!
