Horn Circuit Breaker Location?

[Dave in Houston]

I had to change out my horn ring and apparently tripped the circuit breaker in the process. Chilton's says it's located on the light switch. For the life of me I can't find it. Anyone know where it's located?
Thanks,
Dave

I dont think there is a circuit breaker for the horn you probably blew a fuse. I'm pretty sure the horn wiring doesnt go through the headlight switch anyways and if it did and is on a circuit breaker they reset themselfs and if they dont then you have to replace the whole switch.

Chilton is correct for '66-'73 years. The headlight switch contains an automatic breaker. The bad news is that it is not serviceable. The really bad news is the headlight switch terminal that feeds current to the horn is the same one that feeds current to the brake light switch. You may want to verify that they are/are not working. Later years used a horn relay without a breaker/fuse.

Uh oh...mine's a '74 and the Chilton's manual is '66-'73. I replaced the light switch anyway...the dash light dimmer was bad. Actually only took a few minutes. Still no horn. My old eyes can't read the tiny little letters on the fuse box so I can't tell which fuse is for what. I've got electricity to the little copper contacts at the horn button but still no horn. Is there a relay somewhere?

right next to starter solenoid.unless some one moved it.

There is no horn fuse for a '74. The relay is near the starter solenoid.

Does the relay click when you press the horn? Does the horn work when you jumper power to it?

 

[Dave in Houston]

Replaced relay and still no luck. when I jumper a ground to the contact under the buttonthe horn works. The plate behind horn shows to be grounded but apparently not fully. I'll hook an ohm meter up to it. And yes the horn itself works when you run a hot wire to it. Going to pull the steering wheel next and see if there's something there.

Weird stuff. Apparently the spring and contact behind the steering wheel hub (I assume there's one there) wasn't making good contact. At any rate as I was getting ready to pull the steering wheel I spun it back and forth a few times and thought I'd try the horn again. Guess what, it worked. Thanks for all the help guys.

Heres a diagram of the circuit. It sounds like the horn button is the problem.

 

[Dave in Houston]

It was the horn button and backing plate. Thanks for the diagram. For what it's worth I normally have good luck buying stuff from Tom's Bronco parts but the horn button retainer ring they sent me had to be modified a bunch to make it work. The outside diameter was a quarter inch too big. It wouldn't work till I ground it down the right size. The horn is still a little touchy. There's a spot or two where it won't work until you turn the wheel. Does that make any sense?

sounds like the contact plate is warped or has bad spots in it.
