I have a 1952 Farmall Super A. I took the Alternator off, replaced the three wires and checked it by putting drill on it and it does produce a current. I used the attached wiring diagram. I have replaced all wires on the tractor except for the lights, light switch, and fuse. (Just didn't get that far). I did not put the warning light/diode on either because I didn't have one.
This is a 12 volt, negative ground system. When I go to start tractor, if the two position ignition switch is in, it will not start. If ignition switch is out it will start. This is the correct way it is suppose to operate.
My issue is when I go to shut the tractor off. I push the switch in (it should shut off) but nothing happens- tractor keeps running. I take the negative battery cable off, tractor still runs. I take the positive battery cable off, tractor still runs (tractor is running on its own at this point -No battery cables connected at all). The only way I can shut tractor off is to choke it to death.
Other than the fact that the warning light/diode and lights are not connected (not drawing the alternator down), I don't see why it is not shutting off. There is a white two terminal porcelin block under the gas tank that has nothing connected to it.

We have already talked about some of the colors the unit might leave as clues to its well-being. Now we are going to use our noses to diagnose particular smells. ELECTRICAL SMELLS
