Strange problem

Or maybe a bad earth? Seen some "interesting" lighting displays on trailers which had earth problems 
Nah, they have those chain thingies that go rusty on them.
But I might just have a little road test when it turns a bit warmer.
Hmmmmm............... wonder if it could be an earth fault

Hi Noddy,
are your indicators all working as they should, plus the cancellation switch ?
If so, then maybe the switch for the brake light is somehow sending some volts down the earth , and it's triggering the indicators ? I guess the brake light switch is somewhere near the brake pedal ? Could be the dreaded salt got in somewhere.
Maybe be bollox, but just a guess - !!

you needed a mirror to check that the rear light was on. Even worse ,i would get on the phone to Ghostbusters cos your brake lights are coming on all by themselves
unplug each winker in turn and see if all light stop on, theres a short some wear in the wiring.

Try this
A couple of suggestions
1. What has changed? Has this come about after you have pottered about with something else? Sometimes you disturb something and bad things happen.
2. If your wiring is like most other bikes pull the flasher unit, This should isolate the indicator lights from the indicator power and switches, try the brake, if they still come on it will be an earth fault on the brake cct feeding back through the indicators. (Maybe). If they don’t come on then check switches and relay unit with a multi meter set to ohms (please tell me you know how to do that.)
3. You may have a model that has 2 fuses one for indicators one for brakes. Pull the fuses and see what happens.
4. Selectively jerk your harness about a little here and there checking brakes each time. (Yes Yes I know
)
UGG is right. Mostly work on the Occam's razor principal don’t know what that means but I am sure it would help.
Difficult to diagnose without your cct diagram, but it’s a start.

I suspect a short in the wiring or it would do it with the sidelamps on too!
To test the earth Locate the brown wire at the tail lamp and carefully peel back a little insulation get a length of wire and strip back a little of both ends
Get an assistant out with you and touch one end of the new wire to the bared brown one and the other to the negative terminal of the battery get someone to switch on the Ignition and test the brakes for you if the lamps work normally disconnect one end from what you are doing and try again does it go back to the indicators on? if it does you have a ground problem
If it stays the same with the new wire on an off then do as Ugg suggested but just unscrew the indicator lens and remove the bulb I reckon the wires are nipped soewhere around the tail rather than the front
Do tell when you get a moment ???????
Edit remember to re insulate the bit of brown wire you peeled back!

Thanks for all the suggestions chaps, will try to find time to have a look later on this week and will certainly report back with my findings and a copy of the fire officers report.
