OK guys, bear with me here, bought a gorgeous 2017 T100 three weeks ago and put a few hundred miles on it so far...the horn didn't work when I took ownership which was certainly not a deal breaker but the seller should at least have given me a heads-up...oh well. So I put a meter on the unit and its getting 12 volts at which point I order a new horn figuring the original has gone tits up for whatever reason regardless of the fact that it's virtually new. Here's where it gets interesting...plug in the replacement horn and it works great for about five minutes until I play around with the mounting bracket a bit and then lo and behold, it dies again - completely! Obviously it's not a fuse because that's the first thing I checked and it worked briefly as mentioned. Is there a short in the system somewhere? Should I keep playing with the connections? Anyway, consider me 100% baffled at this point. Any ideas from you Triumph guys with much better mechanical/electrical chops than moi? Many thanks for any advice you can offer. Lack of a horn certainly won't prevent any future rides but every once in awhile there's some cager who you can just sense is gonna pull out in front of you without seeing you (you see it coming based on their 'body language' am I right?) and in those cases maybe once a year you need the fucking horn... Any thoughts?
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.
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
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.
