In my case, my hall sender was hinky. So I wiggle the black connector that
is mounted to the side of the dizzy(while someone else cranks over the
engine) and I would get an intermittent spark. There are 3 wires in the hall
sender and one of mine was worn through and only making contact once in a
while. Switched out the dizzy(cuz it was cheaper to get a complete one from
Scott than getting just a new hall sender) and Voila, spark. Couple of
minutes later and I'm back on the road. Now if anybody has a good used Hall
sender, I can rebuild my old dizzy and have a good spare. Hope this
explains it.
