The fact that it makes any noise is a good thing. Check and double check your connections. Make certain they are clean and tight. Double check the grounding of the horns. I'd suggest a small jumper from the ground side of the battery directly to the horn set. If all the connections are in fact good, remove the covers and clean the points. Do NOT use sand paper or emery heavier than 400 grit.

The horns require a lot of current and dirty points in the relay can cause your symptoms. Before cleaning the points in the horns, try running a jumper wire from the NEG post of the battery to one of the horns to see if it blows, then do the same to the other horn. If either of them blows, you have a relay problem. Remove the cover from the horn relay and use tuner cleaner and a piece of cardboard to clean the contacts. If that doesn't work, use a fine burnishing blade to clean the contacts. The horn button supplies the ground to the horn and the voltage to the relay comes from the Yellow/Green wire. This wire also feeds the horns through the relay points. Tom
