One of the things I find most interesting about
the early motors is the ignition’s. This is one I
haven’t seen before. Thanks for posting your
pictures.
Tubs
Tubs, I’ve been pondering this ignition system, and almost
got myself convinced that it’s not much different than an old
automotive ignition with battery, coil, points, condenser,
less the distributor, of course.
The points on this Elto are Normally OPEN, and they close
briefly on a flat spot on the flywheel cam, then open back up.
I was originally thinking that the coil fired when the points
closed, but now I’m wondering if the brief “closed” period
is the “Dwell” period perhaps, building up current in the coil,
firing when the points reopen?
The Elto coil is rebuilt with a Scintilla coil, as per your drawing?
The capacitor is mounted external on the timer housing, as
per original.
I had the motor firing / running for about two seconds a time or two.
Tomorrow, I’m going to check a few basics, i.e., compression, carb adjustments, etc.,
and see if I can get any improvement.
I was also pondering, wondering what would happen if I bypass the Elto coil,
and hook up my Model T buzz coil. That would fire when the points first close,
so not sure what would happen “timing wise”.
