Got a new coil, points, etc, for a recently brought back to life tractor, 504, now no spark. I've got 12v coming in, but nothing out of coil. Seems like a bad new coil? Constant switched 12v to one side ballast, start bypass wire to other ballast terminal, wire from that terminal to + terminal on coil. Coil -- to distributor ground. Am I missing something simple? Going from old style bullet shaped IH coil/ballast to new, IH supplied coil and ballast with common new style coil.
Background - sitting for 4 or 5 years, with little use and maintence for 10 years before that. Fresh gas and a batt got it running, and new carb even better. Only 1500 hours on it. Ran really good and used lightly for a month or so. Baling hay and started getting some black smoke, not a ton but noticed it, then it died a couple times. Could start and nurse to run with throttle. Figured condensor. Ran the next day, but synptons returned when hot after baling an hour or two. Then died for good just after the last bale at the entrance to the field. At least I got baled.
