Re: 1926 Johnson A-25 Spark Issue???

Be sure to ground one side when checking spark on the other. Test one side at a time. Let us know the results.

If you’re getting spark in one side and no continuity, it’s likely that you have bad contact where the wire butts up against the brass tab at the bottom of the coil. You’ll have to remove the bakelite nuts that hold the wires in and clean the tab and the end of the wire. It’s certainly possible to get spark with this condition, but there will be arcing between the end of the wire and the tab, and that will eventually lead to problems.

Don’t try to remove the coil at this point. Let’s go through some other stuff first.
