Igniter Schematic
« on: December 06, 2017, 08:42:38 pm »
A couple of folks have mentioned SISF’s “Free Power Mod” to me, and after a search I read someone’s comment about a revelation they had as to why their stick coils weren’t working (at the time). Since I may be getting ready to try a set in the near future, it had me dig out an old schematic of the C10 Igniter that someone sent me years ago, so passing it along here for no apparent reason.



Not sure if this is already up here somewhere, but if so, apologies for the repeat. I can pull it down.

I think the primary reason stick coils don't seem to work as well on the C10 as on the C14 is that the stick coils are designed to work with the high voltage pulse generated by the C14's ignition system, and they don't really put out full voltage when driven by the simple switch circuit used on the C10.  They can be made to work, but they probably aren't delivering full high voltage to the spark plugs.

If you decide to try stick coils, be sure you make the ground wire mod.  You need all the voltage possible out of the stick coils.
Remember, much of what you see on-line is wrong or misguided, your task is to filter that out!

connieklr, are you building up your own set, or using some of the T-Cro stick coils?
Wondering if it is possible to buy coils that (are wound differently) and require less power than others?

Ride safe, Ted

I have T-Cro's stick coil kit and it works GREAT.  But I accidentally (without knowing what I was accomplishing) did SISF's extra-power grounding mod way back when I was first doing the electrical additions to my bike, so perhaps I never experienced the low-voltage conditions.

   Yeah, I like TCro's stick coils. In fact I got them YEARS--- ago and it's one of my better upgrades!! :)

Harry, you are a genius!  I've imagined it differently for years, but now it all makes sense. Thanks!   :great:
