Horn question

tcope · Post by **tcope** » Sun Jul 24, 2005 4:07 am

Is there a good/quick/easy way to test the horn on my truck to make sure they are working? Just hook a wire from the battery to the tab? I tried that, but nothing happened. Does that mean my horn does not work, or am I just being dense?

Yep, make sure the horn is grounded and run a wire from the poss post of the batt to the horn tab. If nothing happens, its dead.

I'm assuming the horn is grounded by touching the radiator support. Is that correct?

try loosening the horn mount then wiggling it back and forth a little to make sure you have a good ground,then tighten it back up. run the jumper wire to the pos side of the battery and it should work.
just watch your ears! LOL

Well I didn't hit my head THIS time, but I have done it multiple times while working on the carburetor...

So one more horn question: Can non functioning horns be rebuilt, or is it more effort than it's worth? I'm guessing this is the case, but I thought I'd ask out of curiosity...

I'm not totally sure that the horns are the problem yet, although nothing happened when I connected the wire from the positive post of my battery to the tab on the horn. I might be interested in the one you have, but I think I will mess around with the ones I have first...

You will hear the horn relay click if the
horn is bad, but it's actually getting power.
The relay is easy to hear if the horn isn't
blowing..."click-clack"... If you don't hear
the relay clicking, you have a problem
elsewhere. You can double check with a
VOM to test for 12v at the horn terminals.
You probably have a dirty/bad horn contact
button, or bad ground, etc... The contact
button is under the horn cap, which you can
take off by pushing, and twisting, to clear
the plastic tabs. Don't force!!! You will break
the tabs, and have to buy a new plastic part
for about 18 bucks... The button is a little
brass cyl with a wire attached. If it's dirty,
try scraping it clean with a knife blade, emery
cloth, whatever...Don't break the wire...
BTW...Make sure the fuse is ok...
Not sure what the horn shares with...
The relay is near the horn. Horns are a dime
a dozen at any junk pard, or you can buy them
from LMC, etc, etc... Horns don't go bad very
often..It's usually something else. MK
