Stebel Nautilous Horn Installation

1/24/2010 11:21:30 AM

Last week, I had the unfortunate event of almost being backed over by a Dodge Ram.  I was sitting about 10 feet behind this guy trying to exit a mall, when all of a sudden the reverse lights came on and he starts idling backwards!  Luckily he was just idling…but I was freaking out!  As most of you know, I ride a Star Royal Star Venture, which is one of the largest full-dresser touring bikes on the market, being dwarfed only by a Goldwing and maybe a Victory Vision.  It weighs 850 lb. dry, and I weigh about 215 lb. and the combined weight is over 1000 lb.  That's not easy to backup quickly and get out of the way…so my only choice was to beep my little weenie stock horn!  Well, after about 5 good strong "beeps", he still didn't hear me, so I switched to revving my motor.  OK, so now I'm convinced that loud pipes DO save lives because he heard me!

I have been dragging on upgrading my horn, but now I've re-thought my priorities and decided that a loud horn will always be in the top couple of items I get for any new bike:Biker Buddy Headlight Modulator, Extra rear tail light, and flasher, and now a loud, 139db horn, guaranteed to wake the dead from 10 feet!

Below is a picture of my new horn, mounted up with a little help from SLOWROLLWV on the Royal Star Venture forum - he fabricates a mounting piece that makes installation on my bike a snap.  He offers it in either chrome or non-finished, and holes are perfectly drilled and all edges finished professionally, as if Kury or ShowChrome made the part.  Great work for sure!  SlowRollVW's info: Slowroll01@comcast.net  and cell is 304-261-8663.

The wiring was very straight-forward, which is good, because for some reason I didn't want to install a relay because I've never used one before, but trust me, it was cake (with the right tools!).  First off, you will need a crimping tool and connectors (male and female). I'm pointing right to them.  If you happen to have a Harbor Freight store nearby go there, as I picked up a kit of 150 connectors for $4.  (Love this place!!!!).  You will also need to pick up an inline fuse and holder (15-20amp) which I grabbed at Radio Shack for another $5.

The way a relay works is quite simple:  It's a little black box that takes power directly from the battery, and has an electronic switch that is activated from the original horn wires which opens and closes the gate to let juice run to the Stebel Horn.  We need a relay because the amount of current needed for the Stebel is over and above the allowable limit for the wiring system installed at the factory. So now, when I press the horn button on the handle bars, it's only job is to flip the switch to provide power from the battery to the horn.  If you look at my picture, the thin wires are the ones from the original horn circuit, and the fat wire is the one that carries the power to the horn. It can handle that much current safely.  (Follow so far?)

Now, back to the install…the horn itself came with the relay, and the relays terminals were numbered to eliminate any confusion as to what to plug in where.

Run all of the wires first, then trim to the correct length and THEN install the connectors. Make sure you tug on the crimped connector to insure it's on there good!  This is one device that you want to work for you perfectly when you need it!  You need to run the power and ground wire from the battery to the Relay, then the thick wires from the relay to the horn.  Then you'll most likely need to extend the leads going to the original horn to get to the relay.

As you can see in the picture, I just tucked the relay in between the battery and frame, and it will be covered and protected from the elements by the seat.  Take your time, and run the wires safely away from any heat sources or friction sources, taking care to cover them up as much as possible.

When you plug in the power from the relay to the horn, please note that the horn does have a positive and negative polarity.  The first time I tried it, it sounded just a bit louder than my original horn…I wasn't satisfied, so for "kicks and giggles" I switched the two wires and tried it.  It literally scared the crap out of me!!! 139db is LOUD!

Now I actually enjoy honking my horn, and waking up the zombies in the cars!
