Don, the only specs I can find on that horn show about 18 amps current draw at peak so I would think a 20 amp fuse should cover it.. If that blows then maybe try a slow-blow 20 amp fuse..

Twisty

When I installed a Stebel/Wolo air horn, I gave up on the wiring diagram that came with the horn, and just used the diagram that was on a Radio Shack relay. All the horn needs is a positive and ground connection, with sufficient current to drive the motor. The relay is just a special switch that can handle a large current without burning out. It sounds like you are using the same fused wire that I am; I think it's designed to light up when the fuse is blown. I used a 15 Amp fuse (I know from experience that 10 Amp is not enough); the fuse should be as close to the battery as possible (but still accessible). I ran separate grounds for the relay and for the negative terminal of the horn. Keep in mind that the horn ground circuit wire needs to be able to handle as much current as the positive lead.

Don't fix it if it ain't broke, don't break it if you can't fix it.
