Horn does not work

First time poster needing a little help. 1990 Ford F250 horn does not work. Replaced the horn because it was bad and it still did not work. Checked voltage at the horn and I'm getting 11.6 so I replaced the horn relay, still no good. So I am at a loss, wondering if there is a ground somewhere I need to check.

Thanks for any help!

If your getting power to the horn and it still doesn't work, then I would say the horn is no good. Try running a wire directly off of the battery to the horn and see if it works.

I bought a new horn and tested it, it works fine. I read somewhere that I should be getting between 12 and 14 volts to the horn, this really has me

From: Elk City, OK

it sounds like you are having a ground problem. Clean the rust and paint from around the area were the horn bolts to the body.

Ok, I don't know much about this but the package says this horn does not require a ground. Even tells you to hook it up before you install it to test it. I have had it hooked up not installed and grounded, not grounded and it does not work. Installed and does not work.

So no matter what you do even using a wire directly to the battery the horn does not work?

NO. I have tested the horn running wires straight off the battery to the horn and it works

If you have power going into the horn, and the horn works separately, it has to be a ground problem. A horn is a simple electric motor. Needs power and ground. Since you say it has no ground, it must ground to where it bolts to the vehicle. Make sure it's bolted to a solid piece of metal. You may need to scrape off a little paint to get proper contact. It should also have some type of star washer incorperated into one of the bolt holes, if it in fact has no ground wire.
