Need help please! 56 super 55
Tractor has been running pretty good. Last week it just sputtered and died. Started and sputtered the short distance back to the barn, then just quit. I had previously installed a petronics, new coil and battery and now i have no spark. I have tested the petronics and seems to be working with voltage from 0 -12 volts as the magnet rotates. I have power to the coil, bought an extra coil and replaced the old ballast resistor from the as it was broken. New wires, cap and rotary button, but i cant get spark at the plugs. Suggestions? What am i missing?
 
Thanks for responding. The ignitor was lthe 1st thing i checked. I'll start going back through the whole system again today. I feel like I'm missing something simple. I did notice i have 12 volts on the coil coming out of the ballast resistor even during cranking. I had a 66 and 770 back in the 90's so it's been a long time since I've had to trouble shoot this kind of thing. I put in a new set of points and condenser yesterday just to try....nothing.
