    Question Stator won't charge the battery, low voltage light is on.

    I went out today and realized my battery was dead due to me leaving the battery switch on for a few days, I got a jump from someone and rode for about 1hr without problems, then my radio turned itself off, 1 minute later the engine started sputtering and eventually shut itself off. I got a jump from someone else and was able to ride normal for about 3 minutes and then it happened again.

    Seadoo Challenger 180 2005
    Brand new battery was Only used for one full day with no problems before this happened.
    Starter Relay was replaced same day as the battery.
    Engine was recently pulled to fix SC failure.

    What do you guys think is going on?

    Try slow charging the battery. From what I read here, the Doo's charging system will keep a good battery up while running, but will neither charge a dead battery nor produce enough juice to run on a weak/dead bettery.

    I've gone out with a completely dead battery many times before, got a jump at the ramp and went on to have a full day of fun.
    It's different this time, the battery isn't getting charged by the motor.

    I took it in, they replaced the rectifier and said it was fixed. I went out again, voltage warning light came on, and I'm back to step one. Battery is still not charging. Any ideas guys? Please?

    check the plug above the throttle body, it might have been forgotten to plug it in.
    or the regb fuse has blown,
    or the red wires from the reg have corroded inside the terminal ends

    Thanks for the advise, I took my battery in to have it tested, battery is good. I just took the red and black cables out of the boat and I'm going to have the tips changed at west marine or buy new cables.
    I will do what you said as soon as I get back.
    By Reg you mean Voltage Regulator? The Rectifier? It was just replaced.

    Also, I just fully charged the battery and tested it again, the low voltage warning light is still on. I'm hoping the new wires fix this.

    One question, should the boat be able to keep running if you unplug the battery while the engine is running? I tried it, the boat instantly turned off.

    The plug is in the throttle body.
    I replaced all battery cables, nothing changed, the battery ground wire was in really bad shape though and the red rubber covers on the Starter relay terminals were all melted.

    Can you please explain to me what the regb is and where I can find the fuse?

    Thanks

    If you have a MPEM the (2) 30A fuses mounted on the side of it control charging. Should be above the starter selonoid, ansd have big red wires going to them.
