HELP!! 12 volt conversion from a magnamatic

Recommended Posts

johnmonkey
If I change from a magnamatic ignition to a 12 volt ignition as per the directions in the "do it yourself" section. Would I need my old amature under the flywheel? Do I need any of the wires from under the flywheel? Can I eliminate all of the stuff under the flywheel? I would probably leave the lead-magnet holder because it is heavy and would add to the efficientcy of the flywheel. Any help would be appreciated. Thanks John H

Yes I was refering to the model 19 magna-matic from 1961.Sorry I forgot to add that little piece of information. I was thinking (too much) that I would need the armature wire to go to a terminal on the new coil. I was thinkig that the rotation of the flywheel and magnets would create the pulse of electricity needed to send a spark to the new coil and the new coil would boost the spark for ignition. I'm glad I was wrong. I think I will look in to a rebuild of the model 19 and go with the 12 volt conversion. When I removed the flywheel there were pieces of metal that became separated from the lower half of the armature and I hear that those armature parts are expensive and maybe hard to find. Thanks for your help. John H

I replaced the magneto setup on a 10 Hp Briggs 18 yrs ago by hooking the points to an external coil powered directly from the battery like an older car. Still running, purrs like a kitten. I originally used a motorcycle coil, but recently cleaned up the overall design by mounting a Kohler coil to the head of the engine. Easiest way to fix the problem of a bad mag. If it has points this is the way to go.
