Last weekend I removed the radiator to get better access the the front of the engine. Finished what I was doing, put everything back together, started the car, all was well (so far).

Driving down the road yesterday, tried to honk horn and nothing (it worked fine before). Looked under the hood and saw that I had inadvertently 'smooshed' the wire from the horn rely to the first horn, behind the radiator. Smooshed flat, through the insulation. My bad.

I replaced that section of wire but no horn, just a clicking sound. Could I have fried the relay? Or the horn? How can I 'trouble shoot' the components?

Thanks.

Pete

The clicking sound should be the relay. You probably blew the fuse when you tried to use the horn.

After posting my question and thinking a little, I 'jumped' the relay (from the 'battery' connection on it, directly to the nearest horn) and got 'horn'. It's LOUD standing directly above it . Horns (and ground)are ok.

If the 'clicking' is from the relay (what else could it be?) then it is getting 'juice' from the horn 'button'. Soooo, I have deduced that my problem is either the relay, or the wiring from the relay to the horn (that I damaged and repaired).

I have a plan.

Fuse? Where in the circuit? I don't see one for the horn in the fuse box. I did not say previously but the car is a '63 convertible.

Thanks for the reply.

Pete

the clicking indicates that the relay is working, however, that doesn't preclude the points in the relay being damaged. I suggest that you carefully open the relay, and check all the points. You might just find that they are burned as a result of the short. When the relay is activated, it carries the current to the horns. I don't remember horns ever having a fuse between the relay and the horn itself. Time to get out your test light and check the terminals on the relay before opening it up.

Never argue with an idiot. He'll drag you down to his level, then beat you with experience.

Thanks.

Attached is a 'shot' from the '61 shop manual. I'm apparently in the 'loose connections or broken wire' or 'defective horn relay' world. I should be able to figure that out .

To close the loop; I replaced the relay and did a LOT of housekeeping on all the connections. The horn works.

Thanks to all who replied.
