    Relay clicks when I press the button but no noise at all from either horn. Any ideas for what to check next?

    The horns burn up over the years. Corrosion sets in the internals and locks it up. I took mine apart and cleaned them up then realized the single copper conductor that goes from the + terminal to the coil was melted apart like a burned fuse. Bought new ones from OER.

    Could be an issue with the horn(s) themselves, could be the horn(s) not being grounded well, could be a connection issue on a wire, and/or could be a contact issue inside the horn relay.

    Break out a test light or meter to find the issue(s).

    It's a problem with the horns internally. It's very common. The horn is a one wire hook-up. Check for voltage at the connector end where the horn hooks up. If you got voltage, problem with the horn


    FWIW, OER horns are great imho

    Connect the horn directly to the battery to see if it works. Then you know which way to go.
