Horn problem

[Dennis Mosley]

Hi Guys,

When I built my car a few years back, I ended up with 2 electrical gremlins. One was a right turn indicator problem that turned out to be a bad ground (thanks Steve R) and the second was the horn.

This weekend I decided that it was time to fix that one last gremlin...hey I never use the horn so it never bothered me.

I pulled out my multi meter and started checking for current.

I have 12v to the horn button
I have 12v leaving the horn button when I press it
I have 12v comming out of the dash
I have 12v at the horn terminal
I have NO SOUND from the horn.

So

I decided to rig it.

I removed the horn from the mount and put it in the front seat. Then I took the hot wire from the horn button and attached it to a push button switch that I got from Finish line and tested the current.

Going into the button 12v
coming out 12v when the button is pushed.

then I took the out going wire, attached it to the horn and grounded the horn and pushed the button.....NO SOUND!

So I went to the parts store and bought a new horn....same thing.

At this point frustration has started to set in. I am open to suggestions.

Let me know what I am missing

Just a suggestion. Take your horn and go to the battery. Take a jumper right off the battery to the horn. Then ground the other horn terminal and see if it works. And it is possible to get a bad horn from the parts house also.

If the horn works when you test it from the battery, reconnect it to your original circuit and test the voltage at both terminals of the switch with the load.
