    12V LOW alarm

    Occasionally I am getting a "12V LOW" alarm displayed on my screen when I first start ski. It happened 3 or 4 times so far in the past month. Should I be worried?

    Check & clean your battery connections!! I had a little rust on my positive term and it caused the same thing. cleaned it up and it never happened again

    leave your ski on a battery tender trickle charger if ur not using it alot... maybe ur battery was never properly charged from the get-go... just charge it and verify ur terminals are clean...

    if it still persists, i would next look at the voltage regulator and verify the charging system is working up to par

    The way I read your post and this is what I would do. When this happens again, turn it off. disconnect the Battery cables. Now check the battery voltage imediately...what does it read??? ....and yes you should be concern, its hard to push the ski and jump on it and start it. Jump starting your type of ski with another battery to get it started is a BIG NO-NO ,BTW, I love your jokes....keep it comming! I just checked. You have a 2007 RXP? so I figure you still have the stock Battery? that should still be good?????? post the reading on the voltage, That alarm is "12V low" is I think the state of condition of your battery and Not the charging system, I will dig into it more....

    the voltage will be ok it is the amps that is the problem.
    I get this error whenthe ski sits for more than 2 days. The battery might be a POS but with the trickle charge I dont see the alarm

    I have been getting this warning since new. I changed the regulator and it still flashes once in a while. Most common when the layard is left on the post for a few minutes prior to starting.

    I had the same issue with my 04 RXP my fuse was the issue in my ski .(in the charging system)
    The fuse was good but the connection was loose and discolored
    I cleaned the thermal and pinched down the thermal for a better fit put a
    New fuse in and that fixed my low voltage warning

    Battery Tender

    I keep mine on a Battery tender but my question is why does SeaDoo tell you not to charge your battery while it is hooked up ( besides the build up of explosive gases ) I have done this for over a decade ( with the engine compartment properly ventilated with no ill effects.
