GS500F and the Stebel Compact Nautilus, installation guide..

Discussion in 'Modifications and Projects' started by ginji, May 2, 2008.

  1. It's pretty easy to install on this bike, given that the side fairings can be called cavernous...

    You need:

    A GS500F
    A Stebel Compact Nautilus horn & relay (they come together)
    About 30-60 minutes depending on how neat you want to be...
    A bench vice will be handy too, as will a hammer (relax, it's nothing too bad for the bike...)
    A permanent marker
    Possibly a bolt, nut and washer... I can't remember if i re-used one or got a new one...
    Inline fuse holder & fuse
    Cable ties!

    The original horn is on the left hand side, so you want to take the fairing off that side ;)

    For the first parts I don't have pics as my horn is already installed and i'm writing this post-installation with only pics of the installed horn...

    As I replaced the old horn because it was dead, I threw that away. To take it off (and i'll presume you're taking it off and not keeping it...) just undo the connectors and the bolt. If you can't manage this, then I must wonder how you managed to get the fairing off...

    Anyway, you should be able to see that the horn was held by a flat strip of metal. We want to take that off as well, but first mark with your marker where the flat piece meets the holder on the chassis. Now walk over to your bench vice and hammer and bend that metal into a right angle, you want it to sit as close in as possible, so bend it at that mark you made ;)


    You want it looking like that ^^

    Now bolt it back on, bolt the horn on without the spacer, and start wiring...

    The original horn wires aren't going to cope with the current draw of this horn, so you'll want to run some wires from the battery to where the horn is. As I had other plans for the bike, I ran an earth and live wire from the battery along the same path as the other wires, around the right hand side and then across the front of the engine, but to do this you need to take off the other side fairing, and fuel tank on it's least. Decide what to do, and do it. I used only black wire to confuse later people that decide to do electrical work on the bike ;)

    Run the live wire through a fuse (20A) and then the switching part of the relay and then to the horn. Connect the earth to the horn and then the original horn switch connectors to the control part of the relay. Give it a quick test and then proceed to deal with the noise complaints of your neighbours. When you're done with the complaints, tidy everything up and put it all back together. You'll see how i've tidied everything up in my pics.
