Nautilus Compact Loud Air Horn Mounting

[frenchbiker]

To OP: Just make sure you have a 20 amp in-line fuse close to the battery leads, it draws 18 Amp much more powerful than stock, so over time your stock fuse will blow.
Without relay ( not recommended) it works, but far less loud.

I put mine under the right side fairing with no issues whatsoever...

Found this article today

http://www.twistedthrottle.com/article/articleview/384/1/28/

thats article suggests no relay if im reading it correct, the horn will work without a realy but may not works to its full decibel potential. Fitting relays is good practice and a very sensible thing to do, a lot of DIYers are put off fitting them as they dont understand the wiring, they are very straight forward to  fit , the only additional wire you need for the relay is a hot wire to your battery , the other connections you use are the original horn wires and an additional earth to the frame , they  easy to understand and once someone shows you how , you will be converted. being able to use a soldering iron is handy .

According to the Swedish site www.berup.com, Stebel stopped production of the Nautilus horn... True?

seen this on e bay bet this would sound great on a gtr .i had one on a car years ago great sound ang got loads of attention when it was sounded about a tenner i think.

I've always upgraded my standard horns to the Stebel Nautilus horns. Numpty car drivers just don't take any notice of standard horns.

Very compact and great sound.. haven't had a chance yet to mount it to the GTR, but will before the summer.

What kind of relay should one buy?

Hi Ros,

I always use a 30amp 4 pin relay for the Stebel, but you could get away with a 20amp one though.

But definitely use a relay, standard wiring might be close to it's load limit to run the horn, better safe than sorry.

All the best.
Al.

Thanks for your reply.

Maybe I'm being a little daft, but where do you get one from? Ebay? Can you suggest a link to an example?  i don't much play around with the electrics...

Sorry for being a pain

Cheers

Aaaah wait... You are talking about the Nautilus... I got confused with my Magnum !

Sorrrry!  Will read the subject properly next time.

I blame my ipad (again)

As Bryn posted in another thread ( I think) magnum doesn't need a relay, so I should be able to get away without any clever electrics



Thanks and sorry again

You found one yet Ros?

Dealt with Nippy Normans many times.. I know hw's mainly BMW but a horn is a horn ...

Yeah I fitted a Magnum but without Relay.  I just got confused with the topics.  Might be a good idea to fit a relay anyway...

The Magnum makes a big enough noise for me anyway :)

Air horn would be overkill IMO...

[Bryn]

Ros, just got a Magnum... It's a bit tight as a straight swap.. I've turned the bracket upside down and then mounted it.. Do you find there's enough clearance when the forks are compressed?   

Edit: i think i may put the original back on, and piggy back the magnum... It should fit under the infil panel to right of the tank storage box....

Edit no.2 :  the original is louder than the new magnum    it's going back ,and I think I won't bother   

[viper]

this one would suffice , 4 terminals,     

Earth, battery , existing horn power, new horn

[Ros]

Bryn...

Try it with the engine running.

Then, tune it using the bolt.

And if the original is still louder, then I'd agree. 

I have mine facing slightly to the side so as not to get too much weather in it...

However, mine does make a most satisfactory PARP!

I have ordered my Magnum today - do they all need 'tuning' and is it easy?
I remember the older standard horns used to have a screw and lock nut to adjust the tweet.
