The Stovebolt Site Forums The Shop Area The Electrical Bay Another Horn Question

I honestly wouldn't suspect that the bearing is shorting out, especially given that the horn only blows in one specific spot as you turn the wheel.

Before doing anything more drastic, I would strongly recommend replacing the insulator. The proper insulator is designed with a specific shoulder that keeps it from contacting the bearing. Using a makeshift fix like a straw likely won't be up to that task and will probably lead to the same issue recurring.

Replacing the bearing is not an easy task as they are usually stuck after being installed for seventy years or so.
