    Help Polaris sportsman 570 won't start.

    Installed a winch, wired directly to the battery tested the winch without the bike on for a few minutes. I realized hey I might have drained the battery tried to crank and nothing but trying to crank noises and instrument lights flickered. Jump started with the truck and would shut off once I disconnected the jumper cables. Found 4 out of 6 battery cells dry, refilled and threw it on the charger. Charged to 12.5V. Now the instrument cluster will turn on then try to crank and everything shuts off and loses power. Disconnected then reconnected the battery and the instrument cluster will turn on then try to crank and everything dies again. All fuses are good.

    Is it a relay problem? Is it a breaker? I need help hunting season is just around the corner and I have things I need to get done before it starts.

    Thank you in advance

    Check the fuse block under the front compartment. I had the same issue with a 800 Sportsman, replaced the block and no more troubles.

      Sounds like you might have a bad battery. A hydrometer will tell the tale.

        My Ranger will not run on a weak battery-at all.
        Left me in the back 40 once because of this. Started fine getting back there, then nothing.

        I keep my battery on a tender, but when it's weak, game over.

          If cells were dry, you need a new battery.

            Bad battery. Don't believe it will charge battery until 1500 or 2000rpms.

              Once I try and turn the motor over everything loses power. I go back to off then to on nothing, try to crank nothing. Literally no power what so ever. I take the negative lead off the battery wait a minute and place it back on go back to the switch and I'll get power on the ON part of the ignition then go to crank over and everything shuts down and loses power again and wont reset. I will be replacing the battery tomorrow and I'll try to just run it off a truck battery to the pos/neg leads bypassing the atv battery completely. Any idea why it would lose power and not reset?
