Default 66 Travelall - Delco Remy Horn Cross Reference

Both horns don't work. I see Delco Remy as the manufacturer. It looks like some later model horns might work. Does anyone know where I can get a line on a new set of non NOS horns?

What diagnostic steps have you taken to arrive at the conclusion that the horns themselves are at fault? They might be bad, but there are several other potential causes.

I removed the horns and attached a positive and negative lead and there was no sound.
I did the same test on my 36 Buick during the restoration of that car and the Buick horns made noise. :O
Is there something else? It did not look like the horns could be easily disassembled.
I ended up with some cheap plastic horns while I sort this out
Thanks!

Ok, well that doesn't sound promising for the horns then. Somewhere, back upstream from the horns, will be a three terminal relay. They fail over time especially if they've been exposed to moisture. The horn button and the guts underneath the button serve as the momentary path to ground when the button is pushed. Its quite common for parts to be missing, broken or grime covered to the point of not allowing that momentary path to ground. Then there's the fuse in the fuse block and all the wiring from head to toe of the horn circuit. A problem anywhere in all of those places mentioned can prevent the horns from blowing even if the horns themselves are perfect.

Thanks for the help. The new, albeit cheap, horns do beep. The horn button does not work, so the next step is to go through your step by step process
Thanks again!

I got the horns installed. I looked at the wiring diagram and began working through from the horns back to the steering wheel.

Where the wires connect into the firewall I was able to use my probe and get the horns to honk. This led me to believe the relay was working as it appears where I tested was behind the relay.

I put a fuse in - still no horn.

I pulled the horn button off. Things at first glance looked ok.

At this point, it appears the wires feed into the top of the steering column under the dash. Does this sound correct?

I guess I will be pulling the steering wheel next. Oh the joys I put myself through.

I will review your earlier post to see if I missed anything.

I think your conclusions are correct. If you could post a pic of your horn button guts, we might see something obvious. I don't know how much was changed from that vintage to the early 70's stuff that I'm more familiar with. Its a pretty simple concept, so I can't imagine there being any earth shattering differences. I had to do the same as you many years back with my '74 SII. I found that one of the associated horn wires had been intentionally snipped either under the steering wheel or at the bottom of the column. I can't remember which. Oh thank you previous owners of the world!

I think prior to airbags, horn button technology did not change much. LOL, I have a 36 Buick, 46 CJ2a - with the exception of design changes, the technology had not changed. I will start digging today. :O
