Hey folks,
As the rain is streaming down, I thought I'd share my experience with trouble shooting the reason my horns stopped working. I have spent a good year, off and on, trying to resolve the reason they stopped working. So today, with the rain falling, I headed downstairs to the garage with an "intense" desire to, once again, try to figure it out.
As mine is a 64.5, there are slight differences with the relay being mounted just below the regulator and the horns mounted on either side on the frames below. So, I started with removing the steering wheel and exposing the tiny "springy thang-a-ma-gig" that has long since denoted the 64.5 horn system.
I had "continuity" between this contact point and it's blue/yellow stripe wire where it passes through the firewall plug. Next, I checked B/Y wire for "continuity" between the firewall plug and where it terminates at the relay plug located beneath the regulator. This leg appeared to be continous.
Next, I checked the leg (yellow w/blue strip) between the relay plug and the horns, which proved to be "continous".
The only leg remaining is the power supply to the relay. This consists of a yellow w/black stripe 14 gauge wire running between the battery terminal on the solenoid and the "BAT" terminal at the regular. At this termination, there coexists with the Y/B wire, a short solid yellow 16 gauge wire that supplies power to the relay. As it turns out, I had continuity from the solenoid to the "BAT" terminal. However, there was "NO" continuity in the yellow wire between this point and the relay. I found the break! As it turns out the "factory" crimp at the "BAT" terminal on the regulator had somehow worked loose and was not making contact. So, I took this crimp connection apart, recrimped, and soldered the connection. I now have those beautiful sounding bass and soprano noted sounds again. What's the moral? Be a little more diligent the neck time, I guess!
I hope this is of use to another mustanger.
