Working on a 1937 cub cabriolet. Having a recurring no spark issue. Replaced the coil, plug wires, plugs, points, distributor caps, set to spec's. Engine started a ran fine. Regularly started engine until I had a chance to road test it. Went to start, no spark again. When researching this problem on the forum there was another question similar. I followed the instruction by checking the voltage at the coil wire (disconnected from the coil). From what I understood it should be 3.5 volts. Mine was less than 1/2 volt. The forum did not address what to do if the voltage was below 3.5 volts. Any suggestions on where I can go from this point? Thanks, Jakes

Since the resister is what reduces the voltage I think I would start there (including the connections to it). Charlie Stephens

Hi Jake, You may already have this, but thought I would attach the wiring diagram to use as reference during this post/debug. I highlighted points A, B & C as measurements of interest. gregg

Thanks Charlie, that was it. Finally something that doesn't cost an arm and leg to fix. Thanks again, Jakes!!

Gregg, thanks for your input regarding my problem that turned out to be the resistor. Thanks, again Jakes.
