    Hi all,
    Got an odd problem. Bike (58 plate Daytona) starts and runs as usual, both headlights and tail light work.
    However, the indicators, horn and brake lights have all given up.
    I find this odd, as the switches are in different locations.
    At first, I thought it would be the No.4 fuse - replaced it to no avail.
    Have checked all fuses and connections and cleaned the main earth point under the tank.
    Is there another earth point that I've missed that might be causing these issues?
    Bike is absolutely covered in road crud due to heavy engineering works nearby, so I suspect this may have something to do with it!

    Any help or pointers would be greatly appreciated...

    The indicators, horn & (front) brake light wiring are all within the left hand switchgear loom. May be worth checking that connector initially.?

    I think sometimes the wiring breaks at the horn causing issues with that circuit/fuse.

    Thanks all.
    All sorted. I had already dismantled/cleaned the l/h switches and associated connectors.
    Horn was relocated inside the r/h fairing ages ago, cos it's bloody stooooopid where Triumph put it!
    Turns out that, as I suspected, loads of muck from the roads had got into the rear indicator lenses (where the lugs had broken off), and absolutely covered the bulb connectors in shite. A quick clean and all seems good now - apart from the horn. It worked, albeit pretty feebly,
    then gave up! I can live without that for a few days, but brake lights and indicators are a must for me at this time of year!

    Anyone got a couple of clear lenses they don't need anymore?

    So, I was wrong (certainly not the first time!)
    All worked for a while, but turning the bars fully to the right, it all stopped again.
    One of the connectors to the brake light switch had also broken, so replaced that, but still no indicators, (either) brake lights or horn.
    Just waiting for a set of new switches (thanks to @Lenny675), hopefully this will sort it.
    Diagnostic scanner threw up a P1690 error code, (CAN error) so definately something amiss...
