Farmall M no spark

Posted by astroman on April 30, 2007 at 11:42:57 from (68.112.241.90):

For reasons I have yet to figure out my 1949 M will not start this year. There is no spark. I thought the condenser was bad, replaced that, no go. I found a bad ignition switch and a bad ignition wire, fixed those and still no spark. I checked all the other ignition wires, they are good. I have confirmed that voltage is at the coil when the igntion switch is on. I measured the coil, from the center post to either of the two nuts reads about 7000 ohms, and across the two nuts is 1.8 ohms. Does anyone know what a good coil should measure? Can't understand why so much went bad over the winter... it ran fine in the fall. Anyone have any other ideas to try?
