Electronic Ignition Systems.

Ok you electronics wizards, I was reading about E-boxes which contain the starter solenoid, stop relay, rpm limiter and coil/ignitor module in jet skis, and it got me to thinking:

Do our snow blowers use Capacitor Discharge Ignition?

https://en.wikipedia.org/wiki/Capaci...harge_ignition

And if so, do the snow blowers without an on-board battery use AC-CDI?

And do the snow blowers with an on-board batter use DC-CDI?

I will hang my butt out in the wind first and say, "I don't think so." At least, not in the same way as a lot of marine stuff. Tecumsehs have a solid state ignition module, sometimes. (no points) It's my understanding that it works similar to breaker point ignition but uses a transistor, which is controlled by by sensing when the direction of magnetic flux through the coil changes, to take the place of the points. I may be wrong but I didn't think that module will actually store a charge in a big capacitor.....?

Great discussion on ELECTRONIC IGNITION SYSTEMS for outdoor power equipment:

ELECTRONIC IGNITION SYSTEMS | smallengineinformation.com

See attached.

HS1132TA is "Transistor magneto" ignition (see attached). Is this the same as a "magneto with switching components" or is it "transistor capacitor"? Both discussed in above article.

My guess based on bwright1818's post above is that it is the former type.

no electrical genius but pretty sure there are no capacitors on electronic ignition snowblower engines.
just a magnet and transistor like bwright said. only place I ever saw capacitors connected to a small engine was on welding machines .
have no clue about jet skis
