I have a Ford 9N tractor that won 't start. It's not getting spark. I've had the distributor checked (to confirm points and condenser function - all tested fine). I then replaced the upstream resistor block and jumped the key ignition switch; still no luck. There seems to be a break between the resistor block and the coil (meaning it must be the feed wire but I can't find a break anywhere in the line). PLEASE HELP !

This was posted some time ago, but if you are still having a problem try checking the spring connector at the bottom of the coil and insure it is not grounding out against the breaker point plate retainer ring. I wrapped a small piece of rubber (old inner tube) around the retainer at the top and solved that problem. A little electrician’s tape should work if vibration doesn’t rub a hole in the tape. Another thing I found out is the screws holding the points to the plate get rounded on the underside and the points slip closed after running for a while and do not open properly. Each time I reset them and the tractor starts, it only runs for a while before it quits and the points were not opening again. I gave up and put in an electronic ignition and that solved all my problems. GOOD LICK!
