Richard W: Traditionally, ignition problems are diagnosed from the spark plug backwards to the primary circuit. For instance: If you have no spark, try a new spark plug, or clean the one you have. If a new spark plug doesn't help, check the coil wire or replace it. If that doesn't help, ohm out the coil. If the coil checks out, check to see if the points are working. The points serve to ground the negative side of the coil when they are closed. So what you need to be checking is continuity to ground at the negative terminal of the coil. With the points closed there should be continuity to ground, with the points open, there should be no continuity; or better, with the battery in the circuit, you should read approximately 12 volts at both the negative and positive sides of the coil with the points open (the negative side should be slightly less because of the ballast resistor inside the coil).
If you've already performed a diagnostic on the PointSaver, it shouldn't be your problem, the only thing left is checking to be sure its wired into the system correctly and has a good ground if the unit requires it.
Those are my first thoughts after reading your post.
Thomas K: Thanks for sharing the video, I enjoyed it, like Charlie said, you seem to know how to use it. Great resourcefulness on finding the 104 for less than $100; I could learn a thing or two from you; but like Lew Palma, I think it is best to never, ever, tell'em what you paid (although I don't always follow my own advice).
