  • So I'm electrickerying my lad's Trek touring commuter beast. He built the new LX dyno up into an old rim himself. He started the truing, got pretty close. I finished it off. Dead proud.

    Fitted:
    IQ XS (says 2.4W on it). Lightly used 2nd hand.
    Mini Toplight (single LED, can't be a huge wattage needed)
    LX dynohub rated at 2.4W

    Span wheel while fitting lighting loom etc. Seemed fine, a bit flickery at lower revs, as expected (discussed upthread, i.e. rear light).

    Finished much fettling (had to move a canti hanger, tidying cables etc).

    Now Doesn't work. Not an electric sausage.

    Checked hub on another lighting rig, immediately powered up (Luxos U & Toplight Brake).

    Can anyone help me guess what's gone wrong? Seems like the IQ XS had died. Anyone!?

  • Small wiring glitch? I have a multimeter and can have s look.

  • Possible that the wiring fitment that goes into the wheel could do with redoing?

    That might explain why the hub works on the other setup but not your dads lights.

  • 99% be a minor wiring issue

  • Have you ridden it or just spun the wheel?
    I thought my light was dead when I first fitted it because it was switched off from the button on the rear. You have to have power already going to it to be able to turn it back on again and spinning the wheel wasn’t providing enough. Once actually riding I could switch it on and worked fine.
    Just a thought

  • Checked hub on another lighting rig, immediately powered up (Luxos U & Toplight Brake).

    Can you check the non-working lighting rig on a working hub?
    Ideally just the front light
