My horn does not work

[funoldcarguy]

Hi everybody. My horn does not work. I am going to set about to rewire it. I have a great vintage AAAOOGHA horn that I want to install. However... I can't find any resources online with photos/video for a 38 Ford truck horn. If anybody can point me in the right direction, it would be greatly appreciated.

A '38 truck horn is just a simple "beep" horn and they are fairly easily obtained with a want ad here on the Fordbarn.

Nice truck by the way. I like it.

Here is one way to wire your ahooga horn, I have both the original trumpet horns on my ‘41. I wired the model ‘A’ horn on a separate horn button and relay. Your truck is outstanding.

Thanks for the complements! BTW she has a twin sister that is a 39. I am wondering if I should take the steering wheel apart and try to figure out the wiring inside of that, or just install a horn button on my dash. I hate cutting holes in metal though.

I actually already have the horn, its a vintage ANES aaogha. Sounds great bench tested. Just trying to figure out how to get inside the steering column and where all those wires will be going.

I made a small “L” shaped bracket that I mounted the horn button on and only had to drill two small holes in the dash to hold the bracket. The horn button in the steering column runs the stock horns and the auxiliary button is for the model A horns.

Great looking trucks!

The horn button works by grounding the wire from the horn, very simple.
First check that the wire coming out of the bottom of the steering shaft is intact. Slip a wood yardstick up through the steering wheel, bend it over the top of the horn button and exit back down through the steering wheel. Now you need to check the continuity of the wire with a VOM meter and set it to ohms. If the wire is good the meter will show zero or close to it. If it indicates "1" then the wire or ground under the horn button is faulty.
