    Hey guys, just the other day my neutral light started acting weird. When selecting neutral the light was terribly delayed, this was the first symptom, after a few more miles of riding at speed in 5th gear the neutral light started flashing at random, now it pretty much stays lilluminated at all times. My first guess is that the neutral switch itself is bad, other than the switch itself I would only imagine it would be a wiring problem. Ill soon try to disconnect the wire from the switch to determine if the issue is the switch or something in the wiring. In the meantime has anyone else experienced this? Im also wondering how the light staying on may effect the bike if in fact neutral has its own fuel map, or if the ecu is even taking neutral into account. I would think that throttle posistion, air temp, rpm, and speed would be the only imputs the ecu would need to make its decisions, but then again it may be an emmisions thing to have a different map for neutral...
    thoughts?

    Seems to be a general Husky prob. My green ignition light flashes (intermittent, irregular flash sequence). It started when I installed the Arrows with their black box and the smog plug when the bike was new. I got any number of suggestions at the time, but none worked. Husky´s dedicated service people (who had the BMW `puter ) couldn´t eliminate the flashing light either. So I just gave up. But it´s irritating.

    I would think that if this is a common issue with the manufacturer it wouldn't be husky, more so BMW since the tr650 is in many ways a BMW f650, specifically powerplant, wiring, sensors etc...

    I´m not too worried about who did it (probably the Italian electronics manufacturer). But WOULD like to fix it.

    I have been trying to replicate the issue, the last couple times I took the TR out was for quick trips to the grocery store and it acted normal...
    I have a feeling its going to be a faulty neutral posistion switch. Ive been prowling the internet trying to find said switch with no luck. I found a tr650 parts catalog and it is not listed...?

    I couldn't find in the parts book either. I am using a 08/2012 edition.

    I don't know if this will help, but all I could find.

    I pulled this from here seems like a good place to start.

    Check if the switch is alright first, you will have to remove the sprocket cover first. Make sure your transmission is in neutral

    Undo the screw on top of the switch and disconnect the wire.

    - With the engine off and the wire disconnected, you should get no light.
    - Ground the wire to the body of the engine, the neutral light should come on

    - Start the bike, ground the wire for this but make sure you are in neutral.


    If you get the light even with the wire disconnected, then you have a short in your wiring somewhere.

    You can unscrew it and try cleaning it to see if it solves the problem.

    I took the switch out to give it a look and make sure it had not melted or self destructed, no avail, it looked fine.
    I cant get it to act weird when I can actually test it, for now I have the sprocket cover off so on my next ride when it acts wonky I can quickly access it to diagnose if it is the switch itself or not.
    I have yet to find the replacement switch and the local dealer is bewildered because it is not in the parts fiche. It seems this would be a common switch used on many other bikes, its a simple plastic housing with a metal plunger and spring inside.
