    I thought Prutser had problems with his? Or is this version 2?

    I'm still blown away that the factory went to the design/test/build expense on a critical electrical component for a platform 20+ years past production.

    If they can get the Uber Bean-can sorted i see no reason why BMW cannot begin recasting the 3-lug hub :nod :deal

    Protecting a reputation of longevity and serviceability?
    Possibly the costs vs selling price are sufficiently different to make it worthwhile. The 3 lug hub may be seen as not so attractive to be produced (yet).

    --------
    Changes to the ICU did not involve the bean can specks so there should be no issue with different ICUs and the new bean can (with smaller beans?).

    BMW probably didn't. Bosch did. It's useful on every bike from 79-95 whereas the 3 lugs are only useful on two models from 81-87. I'm betting 3-lugs never come back.

    I got one of the Bosch units and get no spark.

    When I seperate the tree pin connector and ground the center pin of the connector I get spark.

    Faulty unit right out of the box?

    Looks like it.
    Further checks?
    One of the pins should have +~10 volts, the remaining pin should have continuity to earth.

    Square1 .. the bike looks too clean :1drink

    -----------------
    With the bean can unmounted - but electrically connected and switched on, you should be able to rotate the bean cans input shaft and get sparks. That will remove any mechanical mounting problem.

    Thank you ,Warin.
    It was dirty last weekend :-)

    I have 8.84 V on one pin.

    Unit out and connected, turned by hand, No spark.
    Did the same with old trigger unit and it has spark.

    Maybe that's one from the early batch like @Prutser had that was faulty.

    So should I go with another Bosch unit and hope it will be good or...?
    The other option are the cheaper EI/Alpha units that I replaced twice over the years.

    I would try another one. If that fails, then I'd go elsewhere.

    I'm a fan of Points in a Can but dmaster had luck with his new bosch unit and it looks tough other than the few hiccups people have gotten. It looks water proof which is cool.

    Bosch botch.
    It would appear the units are not tested as part of the manufacturing process.

    I certainly will pick up two when things even out with the issues you are all having. I installed 2 Alpha units for a friend and both had issues.

    Very much doubt that they are not tested. Perhaps the testing is not rigours enough, they fail in a way that is untested. Would be interested to see if they fail when the supply (nominally ~10 volts) is at full battery voltage, could be a supply current problem.
