Horn won't work

[larrys40]

Ray, Back the adjuster off if you haven't already. most of what keeps horns working is dirty/loose contacts between the wire connections where the plug in/solder joint, and brushes and brush holders. Use a volt/ohm meter to check for high resistance and poor connections. I've never done it than I can remember, but I'm sure you can take a horn armature and put it on a growler to see if the armature is shorted .

I'm a good electrical guy but I'm sure one of the expert horn guys will chime in.
Check out your connections and hopefully that will cover it!
Best of luck Ray!
