I've installed a Stebel and it won't work.
I've taken eveerything back off and started over, retraced all the wires repeatedly, and can't find a thing wrong.
I've tried 4 different relays, including 1 of a different brand.
If I take the + wire from the horn off the relay and touch it to the + battery terminal, the horn blows.
When I push the horn button, the light on the wire from the relay to the + terminal lights up, the relay clicks, and... nothing.
Although my instructions said to run the - wire from the horn back to the relay, I was told to run it directly to the - terminal on the battery, and it made no difference.
I checked the 2 wires from the horn, touching them directly to the battery and the horn worked. If I reverse them, I get a chuffing sound which I assume is the compressor running backwards. So the connections to the horn are good and are correctly wired.
What else can I check? At this point, I'm sorry I bothered with it at all, though I'd love to have the extra sound (as opposed to the 'eenk' noise the stock horn makes).
Any suggestions?

If you can't solve the problem with the Nautilus, try a Stebel Magnum , which is a plug-and-play replacement for the stock horn. No relay needed; the spade connectors plug right on to the Stebel. It's not as loud as the Nautilus, but loud enough, and considerably easy to install (I did it without removing any bodywork from a 1999 RT). Just make sure that the bell of the horn is not pointed forward, so it doesn't become a water scoop.


Don't fix it if it ain't broke, don't break it if you can't fix it.

hmm......check your wiring against this

(courtesy of moshe_levy)

You should have
1 wire from Battery negative to Horn negative (black)
1 wire from Battery positive to Relay terminal 30 (red)
1 wire from Relay terminal 87 to Horn Positive (red)
connect your original Horn positive to Relay terminal 86
connect your original Horn negative to Relay terminal 85

Its just a hunch.....but if you are using relays with a built in diode and you have the horn button wires hooked up reverse, then when you push the horn button the current would flow through the diode instead of energizing the coil.

Some of the Stebel equipment does not work right out of the box. Check your horn with a direct momentary hook up to the battery. Don't bother trying to contact the factory, it is a waste of time since they won't answer.

Thye op stated that he got it to blow by touching the wire directly to the battery post. There is something incorrect in the wiring he has installed. I enlarged the diagram that came with my horn and hit it right the first time. Don't give up, it will work.

Thanks so much for posting the wiring diagram, as I am about to install one of these horns on my Honda Fit (which comes with a horn about as authoritative as that of an R1100RT).


Don't fix it if it ain't broke, don't break it if you can't fix it.

LOL.....I believe it. Horns have got really pathetic over the years. The one in my new Jeep wouldn't scare a squirrel. I am also planning to toss a Stebel in it.

If you run into any issues or have any questions, my inbox is always open.

Finally had time to check your info against what I've done on the bike (thanks for the input).
My horn negative is connected to terminal 85 (which is also connected to battery (-) terminal) per the instructions that came with the horn. I didn't have the right terminal to connect it, but held it directly to the battery - terminal and it didn't make any difference.
My original horn (-) isn't connected to anything per instructions that came with the horn. (I figured per tests below and the kit providers insistence he has installed successfully this way many times that isn't the problem, but let me know if I'm wrong)
The wire going to terminal 30 has a light on it. It goes on when the horn button is pushed and you can hear the relay click.
The horn defintely isn't wired backwards - I touched it to the battery + and - and the horn worked - when I reversed them, I could hear the compressor running backwards.
Any ideas? I'll try about anything at this point!

hmm......That sounds like the relay is working, but obviously something isn't right. How are you with a multimeter/test light?

You should be getting 12V on terminal 86 every time you push your horn button.
You should ALWAYS have 12V on terminal 30
You should be getting 12V on terminal 87 every time you push your horn button

you need to get full power to the compressor and using large enough wires otherwise it will just heat the wires up.

it should work, no reason to give up.
