I noticed my horn button was starting to fail. So I added a relay. Straightened out the problem with out having to take anything apart. Im on 12v so that was probably cooking the button contact. Horn button has no problem operating the switch leg of the relay now.
What horn are you using? are you 12v or 6v. If 12v a ballast resistor will give 6v sound but will heat up and smoke if the horn is blown for a long time. I noticed this when tuning mine.
