    2008 Ultra 250 Electrical Help Please, need your ideas.

    I appeciate your response to my earlier thread, problem still unsolved and need additional help...
    2008 ultra 250, 174 hrs, fresh water use, perfection til 3 weeks ago...
    Initial battery warning light/buzzer upon startup for a month or so, but engine spins strong and cranks right up, like there is no battery issue. This is a weekend use ski, and warnings have generally disappeared after a couple rides.
    Machine recently developed a misfire after pulling a wake board a few weeks ago, seems intermittent, sometimes at idle, sometimes at cruising speed. Seems to have gotten a bit worse. Can not get machine to full throttle, like a cylinder or two is dragging.
    Replaced plugs with new platinum factory ones, no improvement.
    Off to shop, Wires, coils, fuel, fuel pressure, compression etc. All check ok & within spec.
    Pulled pump, all bearings, impeller in good shape. Fully recharged battery at shop.
    Picked up ski, no problem identified by shop.
    Ran machine on home hose pipe and seemed to run properly.
    To lake today, Machine starts right up
    battery warning alarm again, misfire still present.

    Could a defective battery be the primary cause?..as it was fully charged last week and ski displayed battery alarm at lake trial today.



    My son's ski, anxious to get back to normal, one week til school starts and dealer is backed up 30 days.
    Thanks, I appreciate all ideas or perhaps someone has experienced similar pain.

    OK guys...here's the result after a 8 week wait at 1 shop who was unable to determine cause then off to the Kawasaki dealer....plug wires 1 & 4 bad. To lake tomorrow to confirm today's lake test by dealer staff was OK as described. If problem develops tomorrow it'll be found in the dealer's private office come Tuesday.
