The documentation we have found is very limited. Does anyone know of scope photos of the output of the magneto? I guess the most useful would be with a specified resistive load. He has replaced the ignition coil and is still getting no spark. I'm getting a reasonable resistance for the magneto and can see the points shorting the coil and opening at the right time. I'll get some scope photos, but don't know what I should be getting. Thanks!
