Now that I have your attention....

I replaced the stock horn on my 2015 Ultra Limited with a Mini Beast that has two horns in the same housing. It works fine. For a while.

If I hit the horn in short bursts or hold it for a long burst, it stops making sound. Dead. Nada.

If I kill the bike and turn it back on, the horn works again. Clearly there is an electrical problem or sorts. Fuse isn't burned. How do I fix it so it works continuously.

Thanks in advance.

 

Maybe it has to do with the CanBus system?

 

Not to be a wise a$$, but I think you mean a thorny, or maybe a thorny horney problem .

BTW, love your avatar, I was a big Benny Hill fan!

 

Most air horns are wired through a relay that eliminates this , did this one come with a relay fuse ??

 

Called the thread what I did on purpose. Figured it would grab attention a boring old horn post wouldn't!

Not sure what a Canbus problem is, but I'll look it up. The horn connected to the bike exactly as did the stock horn. Two wires connected to two wires. No relay. Maybe I need one...????

 

I have a mini beast and have had wires pull out of connectors from the engine shaking. Several times I've had to pull the horn, find the detached wire and re-crimp on a new connector end.

 

Current is what drives the horn. Use a good relay and no less than 14 ga. stranded wire. I installed two fiamm freeway blasters (one high and one low tone) and they are easily twice as loud as the OEM. Good luck.

 

You need a relay, it draws to many amps once it gets going.

 

Agreed.

 

You better not blow that horn any more until you connect it properly through a relay. You are on the verge of damaging the contacts on the horn switch on your handlebars because you are pulling way too much current through the contact. Connect the oem horn leads to the coil contacts of the relay, then feed the horn from the battery positive through the relay. Ground the horn at any convenient frame location. You can get 20 or 30 amp sealed automotive relays cheap at any auto parts store.
