Last year I put a new signal tone dual trumpet air horn on my boat. While pulling out of my marina yesterday I hit the horn button and no sound. After getting the multi-meter out it turned out to be a bad compressor motor. I called the manufacturer Fiamm today and they are sending me a new one no charge, no questions asked. It was nice to talk to a friendly person with a quick response!
I also ordered a Wema water tank sender today. That company was very good to deal with also! That's two for two today! I'm sure the next person I have to deal with is going to be great!
