Boat horn won’t stop

[Fishin' DC's]

I had washed down my 2004 Triumph 210 today when afterward the horn started blaring on is own and would not stop. Started as a static sound then built up to a full horn blare. Had to disconnect the front speaker and pull the power wire to stop it. Any ideas on where to start in finding a fix?

Me I would wait until I was sure all the water evaporated then hook it all back up. If it does not go back on I would look for how the water got in to short the connection.

You can speed up the process of drying it out with a hair dryer, and then look for the short. The problem really is not how the water got into the horn which I suspect is the root cause of it making contact internally... You just need a way for that water to then drain out.

Pending the shape and location of the horn, you might be able to drill a small drain hole in the horn which would then help prevent that from happening in the future

Hope this helps?

Evaporation took care of the problem. Horn working fine now. Glad I didn’t pick up the sawsall earlier
