Shower of sparks is a special battery augmentation of spark energy
delivered by a magneto during cranking. I have a work in progress that
I'll share with those who are intrested in this topic. Download the

Be advised there are figures called out in the text that
are not supplied and you'll have to do a little sorting
of the words against the three drawings that ARE supplied.
I don't have time to clean this article up right now but
it's good enough to share on a limited basis. I'm not
going to link it on the articles index until it's finished
so this e-mail message is the ONLY place you'll see 'em
listed.
In my not so humble opinion, S-o-S ignition is probably
the best thing that ever happend to a magneto. If you're
not ready to dump these 1940 devices in favor of 1990
devices, you can't do any better in terms of cranking
performance than to utilize shower-of-sparks augmentation.
