Ignition converstion

[NeptuneMadness]

Does anyone know how, or can suggest parts, to convert an 1941 Neptune Muncie points ignition to electronic? Or can suggest the kind of electronic coil to get? My coil is shot, it is actually disintegrating. everything else is good, so I would like to convert if if possible, if anyone knows how or has done this, please contact me.

Can’t help with the electronic coil question. Wondering if you’ve considered putting a new coil winding on the old laminates? Seen a lot of this being done where original coils are unavailable.

Can you post a photo of your specific mag plate?

Electronic ignition conversion for a magneto,
point ignition was possible by simply replacing
the points and condenser with an Atom ignition
module. I have no experience with them but
Mumbles has. He has stated several times that
his experience with them has been positive.
However the don’t manufacture them any more.
There is a Nova II electronic ignition module
for this conversion. I have no experience with
them as well. Some say they worked for them,
others have stated that they failed in a very
short time. I have been attempting to discover if
there is possibility some other option but don’t
have anything to offer at this time. In any case
you will need to have a good coil.

The Atom/Nova II modules will replace the points and condensers, but not the coil. Newer small engines such as Briggs and Strattons have the module built into the coil but most of these coil/modules are designed to go on the outside of the flywheel. The laminations are arced the wrong way. Finding one to fit the inside of a flywheel is the problem. A coil from a Briggs opposed twin might be able to be adapted to an outboard coils lams but I don’t know. Size and magnet polarity might be a factor in making it work though.

Studying photos of small engine magnetos on Ebay might yield some results. I know there’s lots of cheap ones there from across the pond and they are meant for small engines powering scooters and mini bikes etc.

HI Tom. This is my mag Plate it’s a Repco mag plate

Hey KirkP. I have seen that about replacing the coil on the laminates, I have been trying it. It’s a lot more difficult than it sounds! Plus you have to find a new way to route the sparkplug wire. I haven’t tried to fire it up yet, I’d like to just switch to Electronic if I can find a way. Thank you for your suggestion.

Thanks for the information Boathouse, thats my problem, points and condenser are good, my coil is disintegrating. It will throw a little spark, but not really much.

Try baking the coil on low heat (125 degrees) to drive out the moisture. Then apply 2 coats varnish to seal the coil. This sometimes works.
