    R1100RT Horn

    The horn on My '99 R11RT quit working. Everything else seems to be O.K. Is there a separate circuit with a fuse?

    Hey mine too!
    1) Yes there is a fuse. Fuse 4 count in from left side of bike. Mine was good.
    2) I swapped the horn relay with one of the other four identical ones and it still would only make a "doink" sound.
    3) I pulled the horn off, (13mm nut) checked the electrical contacts and cleaned them although they looked fine. Plugged it back in and still would not work.
    4) Next I tried moving the adjuster bolt on the back of the horn while my buddy pushed on the button. Still no worky.

    Next I will pull it out again and try it directly connected to a battery. Only the switch and the horn itself remain as possibilities. I think maybe the horn be toast. Update later...

    whoops, Roger is quick!

    Probably a little corrosion in the horn switch in the handlebar pod.
