    2005 Ultra 150 Low Battery Warning Issue

    Hey Guys,

    So I've taken the ski out 4-5 times this year but keep having a recurring problem. I've done some research but just wanted to get an opinion on my specific problem. So when I turn the battery on and put the key in the ski I have no warning lights, once I try to start, it immediately starts flashing that I have a low battery. The ski turns over fine and once started the light does not show back up and im running at full power until I stop the ski and im greeted with the warning light again when trying to start. I just purchased a new battery and i'm having the same issue. Voltage regulator maybe? I'm praying its not the stator.

    Normal. On some 'Skis, the light blinks all the time. I guess the voltage sensor is set wrong on some of them. You can use a digital voltmeter to check the battery voltage while not running, then check it again when it is running. As long as the running voltage is about a volt higher, it's charging.

    should the voltage jump immediately once the ski is turned on or should it slowly climb?

    Once the engine starts, you'll probably see a higher voltage after a few seconds. The battery discharges, lowering the voltage, while cranking. It takes a little while for the alternator to catch up and get the voltage back up.

    I had a 2008 Ulta LX with the exact same issue. I charged and charged, I changed to a Odyssey and charged again. Still same issue. I simply got used to starting the boat and immediately hitting the 'set' button to shut the beeping up. Apparently some skis are just very sensitive to the point of inaccuracy.
