Well the ugly problem of charging has come back up again. Back in the spring I was having problems so I rewired, cleaned up every connection, and cleaned up the generator itself. My super A is a 6 volt system. So anyway today I went to mow and noticed that the amp meter had not moved. As a quick check I turned the lights on and it went into discharge. All spring and summer it has been working fine. So I checked all the wires again and everything looked fine. I also went so far as to disassemble and clean out the generator again. I put everything back together and same result. So I looked at the troubleshooting flow chart. Here is what happens. If I do steps 3 or 4 the amp meter will go fully into discharge. The needle can't get any lower. My intuition is telling me that I have a short somewhere, but if I disconnect all the jumpers the flow chart has you put on, the amp meter will show 0, and if I turn the lights on it will only show a quarter discharge. This floors me since I have not seen an amp meter go fully into the discharge side.
So anyway what do you guys think? Has not been a good day. I had this happen, and then my new project jeep is also giving me fits. Ah the joys of projects!

Your description leads me to believe that at least two separate problems exist with your tractor. But start with the test at the link posted.
Luck favors those who are prepared
Great information! I am going to do this test tomorrow night when I get home. I am still at work and won't get home until late tonight.
Well this turned out to be a bad generator. I had to replace it.
Hey Jason, I got me one of those Super A tractors. Still a project.
TN Cub Rescue- Out of the Hedgerows and Barns, and back into the Fields and Gardens where they belong.
Today's generation is so used to getting everything IN a box, they can't think OUTSIDE the box
Yea they are quite a HOOT. Work really well when everything works. But, when something is 60 years old you kinda figure you are doing to be some maintenance.
