Actually, it's as common as dirt. Well almost - electric start lawn
mowers use this to charge their batteries. Like Eric's idea, they use
the ignition magnet that's built into the flywheel. In fact, it might
be a good source for Eric's generator.


Close but not exactly correct. The ignition magnet is external on
the flywheel and just does the ignition. The alternator magnets are
inside the flywheel.

Depends on the engine. I've got a Tecumseh magneto with a
lighting/charging coil. The whole thing mounts on the outside of the
flywheel.
It's off an electric start Snapper walk behind rotary mower.

Makes sense on the walk behind engines I guess since there's not
enough room under the flywheel. Most walk behinds require you to plug
them in to charge.

Some older Briggs had external lighting coils (in 1, 5, and 7 amp
output).

Must be pretty old. I'm trying to remember ever seeing a external
charging coil. Seems like I saw one years ago as a kid but I can't
remember any of the details.
