I have a '65 Gravely L8 with no spark. I tested the cutoff switch and when not pressed it has continuity to ground. I started tracing the short back into the magneto. From the points I disconnected the wire to the cutoff switch, the condenser and the wire to the coil. The terminal on the points has continuity to ground. There is no continuity from the condenser body to its wire lead. There is continuity between the insulated wire off the coil and ground, the coil ground wire was still connected to ground. There is no continuity between either the ground or positive wire of the coil and the spark plug connection on the coil. I did the testing with a digital multimeter. I either got no tone and no reading or it toned and gave a reading of 0 ohms. I am assuming the points should not have continuity to ground since this is the connection that gets shorted by the cutoff switch. I think the condenser is good. What about the coil? This thing has me baffled since 5 years ago it was running. It has sat in the barn since then because of a fuel system problem and I fixed that. The points look clean and in good shape so I can't figure out what could have gone wrong.
