1949 8N - I am utterly, completely, 100%, stumped...

Sounds to me like you fried the coil when you had battery voltage going to it it dont take much. By looking at the diagram if the resistor is good and the points are good it has to be the coil or a grounding issue with it. I would pull the starter apart and clean the armature and brushes and grease the berings first to reduse the voltage draw check the coil for resistance sand all the grounds go thru the points and wires and connectors. Wire it like the diagram. There has to be a reason why you dont run battery voltage to the coil that is why I am betting on a bad coil.

It could be the coil too, but it usually takes awhile to cook a coil, as in it should have started and ran a long while before the coil died. The points won't last terribly long with the key on and the engine not running even with the proper voltage.

Someone switched coils in boxes on me one time with my WD-45, I thought it was a 12v coil right before I went to a plow day. I didn't make a lap before we started loosing cylinders, so I popped the cap off to check the points and the metal arms had even turned blue. I limped it over to the truck and stuck the Dodge style resistor on it that I had stuck in the toolbox after I changed coils, a spare set of points, and that same coil hasn't missed a beat since. But also that was a BRAND new coil... who knows with a older one.

is there a way to hook a plug up to the coil wire on the dizzy and ground the plug and take a jumper wire and touch the negative on the coil to ground and look for spark (bypass the points) key on.

you know its positive ground and you know how to check condensor.it about boild down to points some of newer points just dont line up thus dont fire corectly . your sure your cap and rotor is ok youprobly got a bad coil or a verry woren dist did u try pulling to start these old tractors can be verry cranky i had one once thet ran when it wanted to good luck

are the wires to the coil on correct? if the coil is wired backwards it wont give the propper voltage to the secondary windings.
