I realize he is trying his best to help you but the diagram Mr. Sutton posted is not a true wiring diagram. So in my opinion it is not really of much value for what you have going on. I would say that the wiring on your tractor does appear to be stock as from the factory. I would like to know if the tractor will run with one of those wires unplugged off the resistor? This will tell us if the resistor is associated with the alternator circuit or the ignition circuit. My second request may be a little more difficult. There is a plug with two wires plugging into the alternator on the engine side. It looks like there may not be enough room to unplug it without taking the alternator belt off and sliding the alternator all the way out in its adjustment slot. You may need to pinch the small tab on the front of the plug back against it to release the plug. I would also like to know if starting with that wire unplugged will allow it to shut off properly. Running with either of these unplugged for testing will not hurt the tractor.

If it would just start when I turn the key, then I would use it more often. In addition to a bad case of old age, most of the tractor's original electrical system was simply too unreliable to keep. The main focus of this page is to show how I upgr
