Testing a horn

I have a 69 camaro. How can you test a horn that is unattached to see if it works? Can't you just ground it to the negative battery post and run a jumper to the positive?

Re: Testing a horn

Hmm. Maybe I have a dead horn. If wired up correctly. Can one bad apple cause the other not to work when the horn button is pressed? What usually goes bad with the horns themselves?

Re: Testing a horn

The horn wires are in series with the other. When the horn button is pressed 12vdc goes to both. If one horn fails it will not effect the other unless it causes a dead short. Then you should have a blown fuse.

The horn itself has a type of diaphragm in it that can go bad I guess.

Re: Testing a horn

I have tried to durect wire the horns to see if they are good individually. Horn bracket to neg batt post. Horn tab with a jumper to pos batt post. Nothing. Either one.

Re: Testing a horn

Sometimes they get kinda stuck. Try giving them a few solid raps with a plastic screwdriver handle then retest them.

Re: Testing a horn

I tried tapping on the back with a rubber mallet gently. And rotating it to get any loose junk out. I did get some stuff out. Sand. From both. From the full body off resto I presume.
