If the original coil is still in place, and just has a bad secondary, there is an alternative to the battery system. If you have a coil with a bad secondary and you try to start it, you’re still generating current in the coil primary circuit. You can use that current to fire another coil mounted externally. Detach the wire that normally goes from the coil to the points, and add on some wire to extend it out from under the mag plate. Attach it to the primary lead on an OMC Universal coil, and mount the coil on the block of the motor with the OMC coil ground wire grounded to the block. Then run a spark plug wire from the OMC coil to the spark plug. This may work better if you remove the bad secondary from the bad coil, I can’t remember whether I did that.

Now this is a really clever idea. Even if one had to get some magnet wire and wind a new primary it’s good. It might be made to work with various other coils.
