    Not sure if anyone has seen this -

    But, my right turn signal is no longer working - front or back
    Not when bike is turned on- 4 ways should flash - right does not (though left flashes)
    Not when I hit signal manually.

    I have an Axel computer - and the signal is there, I believe, as the indicator on the computer flashes, but the bulbs do not, nor does the indicator on the tach ring??

    So computer sees I hit the button and it shows it is sending output to bulbs as the indicator on computer blinks on and off - but the bulbs never see the signal - So maybe relay in computer stuck or burnt out??

    I am going to remove power from the computer and see if it resets anything, but so this is the only thing I know of to try, and other ideas???

    Thanks
    Sam

    Process of elimination:
    1. We know the left side flashes. This eliminates the bulbs and grounding on this side.
    2. We know the flasher works and that's internally in the black box or externally at the relay [whichever applies].
    3. We know the right side is not working so one assumes the bulbs are OK, what are the odds of both blowing, and too, the other bulbs are not blown, so there is no shelf life [hour] where the bulbs blowout planned obsolescence wise.

    Conclusion at the troublshooting tree... check ground:
    a. Say there are two wires to the bulb socket. One is ground the other is hot.
    b. With a test light, we prong the hot side [or center contact] of the winker bulb housing wire end.
    c. With a remote wire, we reinstall the bulb, place one bare wire end to the winker bulb housing, the other wire end to the frame or the ground strap at the battery, meaning, a good known ground.
    d. With a test light, find the wire out of the black box that controls the left side and see if this 'back-probing' will light the test light bulb?

    I would suspect first a short in the harness. I have seen this many times and in almost all cases it was a short. If a short is present the mosfet will switch off and will stay switched off until the short is removed. The dash light feeds directly off the same circuit so it will be out along with the rest of the circuit. Begin by disconnecting all the secondary harnesses for that circuit. One by one reconnect the secondary harnesses until the short reveals itself. Once revealed trouble shoot that portion of the harness.
