    Low voltage warning

    I had been getting low voltage warnings, I took the battery out and charged it fully, after charge it shows 12.8 volts, I put it back in and started it and its reading 13.8 volts on the volt meter while running.

    It usually starts giving me a low voltage warning in about an hour,so I ran it for an hour an got no low voltage warnings, the battery is showing 12.6 connected in the ski with the motor off, does it sound like its okay or should I be getting a higher reading while running?

    Some doos have sensitive computers that throw a low voltage warning and there is no problems with your battery.
    I've had it happen on 04-07 rxt rxp gtx and Gti models.
    I've even had it happen on brand new batteries that I charged before install.

    After I get the low voltage warnings, I'm lucky if I'm able to shut off and restart more than a couple of times, that's one of the reasons that contributed to a tow rope getting sucked in, I knew better and should have shut the motor off coming back around to assist the person but I was afraid of not being able to restart it.

    It's a lead acid battery that I had checked after fully charging it, and it tested good, the battery voltage gets down to a point where I can't restart and it should have kept charged while running..

    In Florida and warmer areas I suggest replacing your battery every 2 years. Something about the heat that kills batteries. Sure your going to have some batteries that can last longer.

    I just don't trust them at 2+ years old..

    get a digital VM hooked up and velcroed to the console so you can see the actual voltage reported before the lv warning comes on. I'd say your regulator has a heat related fault. The cost of changing that is small compared to the hassle of needing a tow. Having a spare regulator in your beach kit can be a day save for you or others in your party.

    Your regulator is crapping and it's a slow dive to the low voltage warning
