Well the battery did make a difference, but still no joy.
The increased amperage resulted in spurts of cycling of the points - and lots of smoke. I do not see any realistic way to restore function of the horn , but I do see a likely hood of flames if I were to to continue to apply power.
There is something significantly wrong in that circuit. As I said earlier, someone has wrenched on that old horn before me, tried and failed to fix it I’d wager, maybe even made it worse.
It’s been educational and enjoyable, but I’m throwing in the towel.
Thanks again.
