    horn sounds at will

    took my 65 out for a drive today and the horn decides it wants to honk at will. most notably while driving thru a local park as if to say hey look at me!!
    anyway what would the usual suspect be??  Keep in mind I just put new gauges in the dash.  I did wire my horn thru a relay last fall.  I spliced the relay wiring in under the hood where the wires split to each horn.  It has never done this before so i dont suspect the relay wiring.  Does anyone know where the wiring for the horn runs?  I know it runs down the steering column then under the dash but where to exactly?  The only wires I saw that were affected during my short the other day was to the lights on my gauges and the old wire to the A/C.  I dont suspect that either.  I am going to check my wiring diagrams to see if it shows where the wires run.  I just thought maybe someone has experienced this problem

    The old getting Horny in the park problem.
    Were you turning the steering wheel when it honked or going straight?

    Re: horn sounds at will

    I would look at the horn contacts in the steering wheel.  Do you have an original wheel or aftermarket?

    Money you enjoy wasting is NOT wasted money... unless your wife finds out.

    Leave it the way it is but just make sure you wave every time it honks, every one will wave back at you - - good P/R.

    Re: horn sounds at will

    Pull the horn relay to stop it butt (TS&T), it sounds like the fix will be found in the steering wheel hub.  That's where the switch is and the only place there is any kind of movement that could cause the the contacts to make up accidentally.

    This is why I recommend BB's horn circuit mod whenever anyone is talking about horns.  The stock system takes 12v from the HL switch and runs it through the horn switch, then out to the horns.  When the  contacts in the steering wheel hub go to hell you either get what you have...inadvertent horn honking... or what happend to Sal in Dallas, a solid short to ground which renders the HLs unavailable.

    Here's the  fix:  (After you fix the present switch problem) There's a little yellow wire (#460) that runs from the HL switch to the column.  Cut it and tape up the HL switch end.  Add a ring eyelet to the column end and ground it.  Out at you relays, remove the wire from terminal 85 or 86 that you now have grounded and splice it into the always hot battery wire that you are using for horn power.  Now when you hit the horn button you will be applying ground to the relay coil rather than 12V from the HL switch.  That way when the switch goes to hell the worst it an do is blow the horn, but it can't short the HL switch to ground and cause real trouble.
