Horn issues...
Looking for some ideas on solving a horn issue...horn stopped working
the other day. Checked the wiring, replaced the relay. You can hear
thee clicking of the relay, but no horn. Is it a bad ground? I may be
overlooking the obvious...that the actual horn is no good...

I would check the contacts at the horn itself, they sometimes get dirt, road dust, or rusted up! clean and make sure the contact is ''Tight'' also check the wire from the relay to the horn, mine was broken!! ps, and the ground wire, like you said..hope it works!!

put a cheap test light on horn wire at horn. press horn check for power!
The horns can be taken apart and the contacts cleaned but not a fun job.
double check ground but check that power first.
Could also be the contacts in wheel...

If you can hear the relay, it would seem to be the horn or the wiring going to it. Is it something that gets used very often? Those things can stick together inside. I have fixed old motorcylcle horns by rapping them wood a hard wood block or a soft faced hammer etc... not rubber, you have to shock it!

If the horn has a pitch screw in the backside, try turning it while someone honks the horn or take it off and attach a lead to the spade connector and then to the pos. side of the battery and then ground the bracket to the neg. side. Try turning the screw and smacking the backside of the horn in the center. I've fixed a bunch of old horns this way, mostly mustang and cougar horns but I've also done some earlier model Fords as well. You might also spray some WD-40 into the screw hole. Just fixed one today that had been laying outside in a 69 Mustang for several years, looked like chit but it'll blast you out of the shop now.

Thanks for the input...I'll check out those suggestions in the morning...and Spurredon,
even though I'm an ex-New Yorker, my horn only gets used once in a while, usually to
tell my son to hurry up and get ready to go to school. I'll let you know what works....

If you can hear the relay, I doubt it's the following...the usual reason why the horn doesn't blow.
The following applies to: 1961/66 F100/250 2WD / 1966 F100 4WD / 1967/70 F100/350 =
Underneath the horn button (or horn ring), on the outside of the steering wheel is the horn brush and its plastic insulator. Both are hand pressed into the wheel.
The brush has a coil spring (looks like one from a ball point pen) made as part of it. Inside the spring is a thin strand of wire that is notorious for snapping in two.
Carpenter (prolly others) sell the horn brush = C2OZ13A821A
