295 robin pulsar coil question

[ncfenceguy]

I have a gas Ezgo with a 295 robin engine with no spark. The owner of the cart is a pretty decent mechanic and I own a general repair shop so we are familiar with most systems. The cart in question was having a no spark situation and we repaired or replaced the connections, fixed grounds, etc. We have 3 pulsar coils at our disposal (2 new, 1 on running cart). No matter which one we try, or how we gap it, we only get .1 volt AC. I have decreased and increased the gap beyond specs and still .1 volt. Tried different multimeters, cleaned the hub, checked for main bearing wear in case the crankshaft was moving up or down etc.... My question, is there something I'm missing or something that is missing on the crank? I see the hub with a notch cut out that I'm guessing creates a Hall effect? There is no magnet or dissimilar metal supposed to be in this hub slot? The sensors have been disconnected while running the test, but only .1 volt AC on all 3 we have tried. Thanks for any insight!!!
