    Hi I've got a 2008 speed triple 1050 which I bought last year. Had charging problems with it replace rectifier and alternator. Was OK then had to change alternator again and now its gone again. Any ideas why this keeps happening ?

    Did you replace your battery? a faulty/weak battery can often be the cause of alternator and rectifier to fail.

    No I haven't was thinking this .. If I charge battery overnight it starts the bike then ride it to work battery doesn't start the bike when I arrive ?

    I would start by fitting a new battery.....its way cheaper than replacing the alternator....again!

    I had a similar problem with my '05 bike: replaced the fitted regulator, that died as well. Fitted a new reg & alternator (Which was showing signs of burning), worked fine for a few weeks then same problem. Had a new battery, but both the new & old are in good condition.

    I then bit the bullet and carried out a resistance test, to make sure the alternator was ok.

    On my '05, the regulator is on the right hand side, next to engine (literally!). The helpful people on here told me this is a design flaw (Hot electrical component next to a hot mechanical component!!) and for the refresh around 2008, Triumph moved it.

    Might be worth checking where yours is. It's plausible yours is a late pre-refresh model & so still has the dumb-ass location. It'll either be on the right hand side, mid-engine or lower left hand side. I replaced the dead regulator with a new one & relocated it away from the engine & has been faultless since.
