Technical 6 or 12 Volt Horn??

Just how do to prove a horn is 6 or 12 volt? Question is posted by an electrically CLUELESS person. Bob

 

I don't have a clue unless the horn is marked but the horn doesn't care how many volts go to it,,a 6 volt horn with 12 volts will probably be louder. HRP

 

Really louder eh? Hmm I mite have to try this. Hope this wont kill this old 6 volt horn. What if you use a resistor to cut the power down when crossing the horn?

My friend has a '53 Chevy with a 6 volt horn and his charging system is converted to 12 volts. Horn sounds loud, but I think it's just the way the horn is designed. It's so loud, I'd use it on my T Bucket, if it was smaller.

 

Also normally a part should be marked 12 volts, if not could be six. But not always.

Unless you like leaning on your horn for 10 minutes at a time, the 6 volt horn will work happlily at 12 volts.

 

Sometimes a 6-volt horn run on 12 will sound "overdriven", a lot like cranking up the volume on an old radio until the speaker distorts. If the one you have does this, or sounds more like a buzzer than a horn, there is normally an adjusting screw for the breaker points in the horn, which can be used to change the pitch of the horn to a more desireable tone. It's normally on the flat side of the magnet housing, and probably has a lock nut on the adjusting screw.

 

6 volt horn on 12 volts sounds like its been goosed. Will work forever but don't sound good.

 

And probably a 12V horn operating on 6V won't have much sound, if any

 

Well as with all things electrical it is worth its weight in scrap. Bob

 

Nobody knows???????????

 

In the few years I've played with cars I agree with this post. Beep Beep!

 

Hook it up to 6v...if it is a 12, it will say something like "zzzBLEAHz"
then hookitup to 12, if 12 it will say "honk", if 6 "HONK!!"
Most honk type 6's will be fine on 12 unless you use the horn like a third-world taxi driver.
A 6V Ahooga will pretty much skip the "ah" syllable on 12, as it spools up at about the speed of light, and will also scare hell out of your dog.

 

Thanks Bruce, this is one of those old Kattle Kal Bull/Cow horns with a lever to effect the tone. Bob

 

Holy Cow! I've got one of those on my 1939 Ford that was there when I got it in the 70's. There was no lever so I hooked the cable to the emergency brake which was not hooked to the 57 Chevy rear. I have no idea how many volts it is but it sure would call cows and scare the neighbor's dog.
Don't help stopping in an emergency but everyone knows I'm about to crash.

 

my horn on my 41 olds is marked 6 v it works just fine off my 12 volt system.

 

Ok, so it doesn't matter 6,12,24,48 volts. The horn is on "That site" if I get one more question about its voltage it gets crushed and scraped. Bob

 

I can attest that putting 12v to a 6v horn merely makes it somewhat louder. As previously stipulated by above comments, you can probably hurt a 6v horn by holding it down for too long, but that's not likely to happen - after all, you're a HAMBer.

 

What is IT'S voltage 37kid?

 

That is my ORIGINAL question, it is unmarked, I'm clueless to things electrical, I fix things with hammers. bob

 

Well hook a hot wire to the horn wire or screw sticking out and touch the horm bracket or body to metal on your car, 6V or 12V then pull that lever. Don't aim it toward your ears. If it does not go Mooouuuooo then use the hammer.

 

We always got 6 volt horns from the junkyards to put in 12 volt cars because they were louder on 12 volts.

 

It has two wires, will it moo before the fire starts? Bob

 

I run 6 volt horns whenever I can, they make it much easier to get the attention of the driver that is texting next to you.

We had a 6 volt horn on a car we took through a wedding one time, my wife couldn't resist honking along with all the others in the "parade". It made some very interesting sounds as it was dieing, not sure a "moo" was amongst those tones though. I didn't see any fire or smoke, but it was under the closed hood, so who knows? Its final sounds, followed by silence, left little question about its condition. Gene

 

37 kid, speedway sells a little book called how to wire your streetrod 7.99 this is a very informative booklet easy to follow.

 

FWIW, I had one of those, and it works fine on 12V. I need to look around and see if I can find it...it's been sitting in a box somewhere since 1990. If I can find it I'll see if it'll work on 6V, since my coupe is still running the OG 6V +ground electrics.

 

Thanks, saves me the risk of burning up mine. Bob
