    Hi all,


    My factory fitted heated grips stopped working. Fuse was fine, service was due, so I asked the workshop to fix it. The complete ******* have wired the grips direct to the battery somehow, missing out the ignition switch, so now if I accidentally leave the grips on when I leave the bike, I come back to a completely flat battery. The workshop has no idea how to fix the issue, so I'm going to have to do it myself.


    Can anyone describe to me the route of the wires from the battery to the grips and back, so I can try to re-set it to what it should be?


    Cheers,


    Professorbug.

    Hello Professorbug.

    I realise this is very late, but I came across your post when searching for information on this very subject.

    I've just fixed my factory-fitted heated grips (07 Sprint ST 1050). I figured out the circuit diagram and took some photos in the process. If you're still interested, reply here and I can upload a few things with some explanations.

    In (very) brief, the factory fitted heated grip wiring loom should plug in to the special socket poking out of the wiring loom inside the fairing on the left hand side. The standard setup has a relay that switches on when the ignition comes on.
