well thank you, tho' its sort of over my head, its the best explanation of what might be going on with my bike! 35k miles w/o a problem, i guess i was due...it always was sensitive to not starting cuz of a low batt'y, but this time i KNOW the batt'y is UP, but only turns over...spark looks weak to me, i expected a bold snap and sharp blue-white color...it had sat inside for over a week, but so what? my old '70 can start after months of sitting! oh well,test equipment needed ! gonna be too snowy to ride soon ( the bright side of it all ? )

Thanks! I should mention that having no scope, there is an alternate test for the pickup coil: If the tach bobbles around 200 RPM while cranking, the pickup coil is working. But if the tach does not move, then things can't be narrowed down so easily. Either the pickup coil is bad -- or -- the tach circuit in the ICU is bad -- or -- the tach itself is bad.
