Thanks, Steve. I'd already put the project to rest for the day when I first posted because she's flooded to boot (of course!). The mag's on the tractor right now, and there's a few things that will be better/easier to check while its on.
But I'll put the analytical skills back to it tomorrow so that, with any luck, I can nail the problem down and get on the horn Monday to get what I need to get her fixed. MagMan'll be the first call.
I'm thinkin' while I'm at it, I need to eliminate a bad contact in the cover. Also gonna try checkin' for continuity to ground at the ground post (with the wire to the switch disconnected) while turnin' the engine by hand. Thinkin' that I should have continuity there when the points are closed, and lose it when the points open. If that's the case, I can eliminate a short in the wire from the points to the condensor. That'll pretty much leave the coil and magnet, or something affecting them.
Not sure that'll work 'cause the ends of the coil body are smack up against the magnets, so I'm not sure how or if it's isolated from ground, though it seems it would have to be. I'll just keep approachin' it as a learnin' experience.

They were horrified (we lived by the railroad), my mother thought the worst: "He’s been run over by a train, he’s gone forever!" Where did they find me? Perched up on the seat of the tractor. I’d probably plowed about 3000 acres (in my head anyway) by the time they found me. This is where my love for tractors started and has only gotten worse in my tender 50 yrs on this “green planet”. I’m par
