    Thanks for the update - Has it been confirmed that it IS the
    Ignition Switch wiring that is causing the problem you reported ?

    Cheers  :821:

    No. I have other things to work on.
    If I keep my expectations tiny, I don't end up so whiny.

    I just checked my bike and apparently the problem isn't a bad sidestand switch.  My bike will start with the side stand down in neutral, but as soon as I put it in first gear, the engine stops - unlike NC Scooter where it continues to run when in gear but stops after the clutch is let out a bit but before the clutch starts to grab.

    I would try just for S&G's disconnecting the negative battery wire for a few minutes and then re-connecting it and see how it acts.

    STJIM : Yes, as described previously, that's how it should be.

    Appreciate you're trying to help, but NCScooter has NOT said his engine runs in gear
    with the Side Stand down, which it shouldn't do.

    He says the has other things to check, but why his engine should cut out
    as soon as the clutch is released ( when the clutch switch would operate )
    when the bike is not moving, with a gear engaged, and the side stand UP,
    is a mystery to me  :027:  That's NOT how the safety interlock should work.

    The suggestion to try disconnecting the main Battery Negative terminal for a few minutes
    and then reconnecting it is worth a try - other Members have reported that doing so
    has fixed some electrical gremlins, but without any DTC's it's difficult to know what else to suggest.

    Cheers  :821:

    I may have flubbed up on the DTCs. I disconnected the (-) battery cable for 15 minutes. About 5 in, I said to myself (I knew it was me b/c I was wearing my own underwear) self, that just erased the DTC codes. Anyhow, when I hooked it back up, there were no codes and she started and seemed to work fine. I'll have to get her off the trailer to road test her. What a maroon I am.
    If I keep my expectations tiny, I don't end up so whiny.

    Padding the post count. Is there a DTC for the ignition wire problem/recall? I don't have much confidence in a bike with electronic "gremlins" or whatever you want to label as unreliable.

    There's no specific DTC for it - but a variety of DTC's might appear.

    If you read up on the Ignition Wiring problem you will see it's basically down to a bad design
    where an "incorrectly" routed wiring harness can get damaged, with any of the wires in the harness
    becoming severed, which can result in complete loss of electrics and the engine cutting out !

    ( Why I am so insisitent that every Trophy owner MUST have this checked ! )

    The "Disconnect and reconnect main battery" can be related to common computer problems
    where the solution can be to "Switch it off and switch it back on again"
    which often allows whatever the system is, to reboot at its default values !

    "They" say there is no computer program without "bugs' , they just haven't been discovered yet.

    So sometimes the program for some unknown reason / combination of conditions can go off the rails, so to speak.  Some programs use a "watch-dog" timer that causes a reset if this happens.

    I had a Dodge truck that had this happens occasionally, maybe once a year - the idle woud be real low and the car woud stall when I stopped.  I had a friend with a similar model and he claimed it was because the battery needed charging.  He would take his battery out and would charge it on the bench and when he re-installed it, the problem was gone.  I woud just disconnect the negative battery cable for a while to clear my problem.  When I told him this, he said ; "But I charged the batterY".

    If disconnecting the battery clears NC Scooter's problem, it's the first time I have heard of a motorcycle with this fix.
