    Hello fine people

    I rode off to work this morning and on turning left it seemed that my indicator developed a bit of a kind of its own. The left indicator light on the instrument panel stayed on and the indicator itself was flickering faintly. When Indicate to turn left the light flashes fully as it should. Then once I cancel the indicator it goes back to flickering. The right hand signally works as it should. Triumphbhave suggested that I book it in to go on the diagnostic malarkey and have said the head technician says it could be the instruments or the wrong look. Has anyone come across anything like this before? Much obliged.

    Just a quick suggestion, I had a similar thing and it was a sticky indicator switch. A good dousing through the housing with a spray cured it.

    much obliged sir :) I will try that. I doubt triumph will tell you these things. They said it could be the instruments and that I needed to put it on their diagnostic tool (at £120/hr) I mean it could be something like that but i will try your way first

    Also check there are no exposed wires in the cabling that is shorting out.

    Hello Sir :) So I tried the things you said and unfortunately it has not worked. I took it to a local mechanic and he was able to tell me that it is the instrument cluster. would you put a second hand one on? (bearing in mind that the milage wouldn't be the same) or get a new one? or something after market? is there a way to share this thread without having to start a new one?

    @David Aldworth The thing about fitting a second hand unit is it is untested and could be as bad. Its not going to be a cheap repair. I would tend to get an authorised Triumph dealer to run the diagnostics first and hope for a repairable solution.
