Hm... I've been a bit unclear ... I want to measere the amounts of
discharges per time-unit. More precisely : the amount of sparkplug
discharges per revolution of the front- or rear wheel of my motorbike.
I've done a measurement this morning, with a zener and a pickup coil, but on
the scope it isn't a "more or less" clean induction: in fact: it's a mess !
Is this more clear ?
