66 SS Horn

Okay, so after getting my steering back together with new turn signal and new horn ring set, I still had no horn. So up to the front to work on the horn itself. After a while on a direct 12 volt current, I finally got the horn to make sounds. So back in, and still no horn. I finally replaced the horn relay, but now when I hook it all back up, the horn sounds constantly. It won't shut off. Below is a picture. The one relay to the right of the green wire had a black wire attached to it. But like I said, when connected, constant horn. I connected everything as it was when I took off the old relay. Any ideas??

Sounds like your problem is in the steering column. Pull the horn cap - ring off and check if the round contact isn't grounded out.

Horn

Agree, sound more like a problem in the column than anything else.

Yep, that's what the other forum said as well. I pulled the horn ring and those parts back off, but I reckon I'll have to pull the steering wheel back off as well and see what's underneath.

Success! Yep...I had to take the steering wheel back off. Got everything pulled and sure enough, when I put it back together last time, I caught the ground wire in the steering column stuff and it was grounding out. That and the replacement horn ring set is not quite the same. The little "tabs" on the original horn ring that goes between the horn spring and plastic washer thing apparently are a key to making it work properly. The replacement did not have the little tabs on it. If this doesn't make sense, I'll try and get some pics someday.

Okay, so now that it works, how do I make it work better. It kinda sounds like an old man yelling at his old wife in the retirement home. I don't know if it's the horn itself, or the wiring, or what. Any ideas?

Also, in the manual, the schematics allude to a "high horn" and a "low horn". I only have one horn, but I do have a pigtail off of it that goes to nowhere. Am I supposed to have a dual high/low horn setup?

The extra horn was an an option, standard on more expensive cars.

To see if yours has issues with voltage dropping off from a bad ground or just a lot of resistance in the wiring use a jumper cable made out of ten gauge wire. You then touch the battery's positive terminal with one end of the wire and the power spade with the other (pull factory horn wire off first). If you have a freshly charged battery and you don't think the horn is cutting it one out of a bone yard is easy to acquire . The factory used the same horn from 1953 to present.

There are also diesel electric train horns, wolf whistle, and the popular Aoogah horn used on Ford model T's only made to work with 12 volt systems all for sale in the pages of your J.C. Whitney catalog.

Okay, here's a few pics of my horn. How do I know if it's the low or high horn?

I have the same problem. I replaced the T. S. assembly and hooked up everything.
Sounded like Joshua was under the hood! The ground wire got crushed when I tightened down the wheel. One must be very careful with the install. The horn is disconnected. I can't get the new tight fitting T. S. assembly off. I may install a mini horn button on the column. I saw cool little unit on Ebay.
