I've got a 1974 IH Cub Cadet 1450, I went out to mow my lawn today, and the engine cranked and cranked without firing.
After some simple diagnosis, I find I have no spark. I'm not 100% on how the ignition system works on this one, so I'd like some help.
I've got ~14 volts going into the ignition coil. The secondary wiring on the coil reads 7,500 ohms, and the primary reads 3.5 ohms.... which is pretty high on the primary, isn't it? It is for a car, anyway... (Note, I checked it while still hooked up to the tractor)
If that is within normal tolerances for this style of coil, without a distributor, what sends the signal to fire?
Thanks!
