    Hi.
    Trophy 1215 SE owner.
    When pushing forward or back and reversing into garage, steering on full lock to the right with ignition on, I get a power loss.
    SatNav goes off. Headlights go off for an instant and I can hear relays clicking under the seat.
    This is only on full lock to the right.
    I've checked and pulled cables to try and imitate a full right lock but I cannot repeat what happens.
    Seems like an earth fault or something rubbing a stripped wire.
    Has anyone else come across this?
    Any suggestions?
    Might be a trip to Carl Rosner on the cards.
    Cheers.
    Wayne.

    Definitely sounds like a broken wire or bad connection Wayne. Unfortunately they can be a pig to find sometimes.
    I’d be having a look around the ignition switch area to start with as it sounds like a main feed failing.
    It might get very expensive to fix if you’re going to get a dealer to have a look, unless it’s warrantied of course.

    Given your symptoms, it's most likely the Key-switch harness.

    On Speed Triples there was a very common issue, where they clamped the harness at the headstock - there was insufficient slack and the wire conductor(s) ending up breaking internally. The solution required repair of the wires and washers under the clamp to give a little strain relief.
    I don't know anything about the Trophy but given Triumphs' propensity to do things commonly across models, look for something similar. At the least,. when on full lock, look to see which particular harnesses are under strain and that should lead you to your issue.

    Hi guys and thanks again for your help.
    Yesterday I made the decision to tackle the problem myself.
    So after taking the screen off and taking off the complete dash, plus the cable tidy around the ignition key switch, I had room to pull and push a few cables and looms.
    I actually found it!!
    You were right D'Ecosse, it was the ignition key switch harness.
    Where the front brake line crosses over to the left of the bike, there is a 90 degree bend before it's attached to the headstock. This was rubbing on the wire loom that comes out the bottom of the key switch. I found the other end of the wire loom under the lockable left side compartment where it plugs into a square multiplug. I unplugged that and got the loom free of the brake line. Re-routing it over the top. However, I noticed that three wires within that loom were badly damaged so I had to cut back the plastic sheath, cut and re-solder the wires and using heat shrink sleeve got everything back as it was.
    I put everything back together, switched on and tried the steering to the right and left a few times and everything stayed on.
    I think I saved myself a few pounds there.
    Thanks again.
    Wayne.

    Well done Wayne, sounds like you’ve done a very professional repair there, don’t it feel good to do stuff like that yourself saving time and money. :p
