Okay, so I got the new starter switch today. It did the same thing as the other, clicks but does not spin the starter, which tested okay on the bench. However, I have located the smoke I had before, which is the temperature sending wire, which smokes out when I turn the key or when I jump from the battery right to the starter. I know I have to replace that, but is that causing some sort of interrupt in the ignition switch or starter switch that it would cause it not turn it over? Doesn't seem to be connected to the system anywhere. By the way, when I jump from the battery right to the starter, it does not engage. Just sparks and sits there, even though it did work on the bench.
The tractor was converted to 12v before I got it. Has an alternator, 12v battery and a 12v coil. However, there is still a resistor in the coil circuit from the ignition switch, which seems to be weird to me. I couldn't tell if the starter switch was 6v or 12v- it doesn't say anywhere. It ran fine before getting it stuck. The starter appears to be original, which would also seem weird since the rest of the system is 12v. I could not find a voltage regulator anywhere in the system, at least not what I could see. That also seems strange.
Any ideas? The crank/flywheel spin just fine, it seems, so i'm pretty certain the problem is not mechanical. Looking at the wiring diagram for 12v systems and 6v systems is not giving me any clues.
