2016 R1200 RT - horn shorts out?

[ranbush]

Another discovery on the new-to-me 2016 R1200 RT. Yesterday a driver runs a red light in front of me (very common in the San Fran Bay area these days) and I give her a loud blast on the horn, and the horn dies after about three seconds. Didn't work again until I turned the motor off and back on again.

The horn doesn't short out if I just beep-beep-beep but a long beeeeeeeep kills it. I'm assuming it's the horn relay, but the schematic in the Haynes manual doesn't show the horn relay, and the text section about the horn just shows removal of the horn, nothing about the location of the relay.

I'm planning on installing a Sound Bomb anyway, but I doubt that the OEM horn is the problem.

Can anyone tell me where the horn relay is located on a 2016 R1200 RT?

overload to canbus explains reset after shut down. Horn may be bad, but I would also check connection to horn make sure tight and clean.

Yes, and the best reason yet for wiring aftermarket horns direct to the battery, through a relay controlled by the OEM horn circuit. You get a louder horn and no CanBus cutout.

Thanks for the replies, Gents.

If you have to honk your horn for longer than 3 seconds.....

Have you ever come upon a herd of cows in the road?

…encouraging a Canadian moose to leave the roadway…

Okay, you've got me there on both counts.

And I will add that cows and moose are a LOT smarter and attentive than most California cage drivers!

I know yours is a lot newer than mine, but I had similar problems on my 05 RT and it turned out there was a recall for it.

Spoken like a true Texan. Be careful how you honk at the bulls.

I once tried using the horn—a loud one—to convince a Jellystone bison to exit the roadway, at a distance of 70 meters or so. His reaction—holding his ground while head-tossing and pawing the asphalt—convinced me I needed more distance between us and more time to let him decide to mosey on. The scenery was beautiful while I waited…

Yeah, good call, Sir. Could've gone real ugly for you, real quick.

Thanks again, still hoping for some info on where the horn relay is located, or info on which connector is the OEM horn circuit that DeVern mentioned.
