Earthing point for Stebel Nautilus

[Marks adventure]

Fitting a Stebel Nautilus horn to my steed.

Have i got to run an earth from the battery or can i use another earthing point?

There's a bolt near the old horn, can i use that?

Thanks in advance

Bolt it to anything metal on the bike and it will be earthed just fine, there's no need to return the earth back to the battery.

Run a separate lead back to the batttery and also a feed if you can switched by the relay. Horns take a lot of current and any slight voltage drop will imparr performance. You only have 12 volts to start with so loosing even one under load
aint gonna hep you frighten the tin box men to death!

Run a separate earth
Don't run a separate earth


Aint you glad you asked



........both ways will work just fine.

Thanks guys. I've run a positive to the battery but going to use a bolt by the old horn as an earthing point, I think, unless someone else says otherwise

See how you get on.

You MIGHT need a relay.

The horn may well 'Beeep' OK but a concerted BLAST might trip the Cabus to safety, useless and silent until you turn the ignition off and on again....

Forgot to mention I've fitted a relay

I believe on the 1200s a relay is NEEDED due to the canbus fluid.

and I've oiled it

I tried it without a relay and it worked - Once... Then tripped the Canbus.

Fitted the relay and now it works every time. Result!

So you ran one cable from horn to battery for the positive, but not for the negative . Weird. Is this some kind of weight saving thing?

If it don't need to go there don't fit it.

The bike's own frame makes a perfectly good return wire. Even the starter has no negative lead.

The starters next to the battery and is bolted to the engine which DOES have a seperate earth lead, the original earthing point means it's got to find it's way
through every thing to make a circuit and when it's in use (the horn) your bound to loose a bit.
