Horn Conundrum

Did you figure out? Mines doing the same thing

 

Is the horn in on a rubber mount - ie isolated from earth? If you remove from the bike and leave it hanging - does it work?

 

There are! Seems like a fairly common issue here.

It’s on a metal mount. I have a 2011 Thruxton, I just purchased. The oem horn was doa. I put on a replacement. It worked for about a week then died. Both connections appear to have good current. I tested with an un-mounted horn and it honked.

 

Just out of interest - are the horns marked for polarity?

 

Good question! I don’t believe so but I’m not near one at the moment. Fwiw: the tabs are the same size as well

 

Yes, if you wire a horn the wrong way round you will get negative noise.

 

On some cars - if the negative feed is on the live connection - when installed the live can go to the earth path rendering the horn inoperative. Just a thought..

 

Horns...... I saw recent posts ref horns that can be heard , and a recommend of the Denali sound bomb mini....( I have a 2008 Bonnie 865 ...... horn = wet faxt !)
I ordered a Denali from Sportsbike Bristol....Excellent service , by the way.
On coming to fit however in the original horns ' position..... The Denali is slightly bigger than the poor original...... I was not happy with this positioning.....
My Bonnie has a Triumph supplied , and very substantial windscreen bracketry..... The new horn , using the 2 extension brackets supplied , paired up , enabled me to fit the horn behind the screen very neatly. A quick job then to extend the wiring with shrink fit waterproof connections....
Result .......Very Loud indeed....! Hoping my £25 investment will help save me , next time I feel ' that driver hasn't seen me ' etc Safe Riding to you all.
