    2005 Polaris 500. 3000 lb winch. Was working great. All of a sudden if I try to raise or lower the blade, the engine dies. If I hook a battery charger to the winch, it lifts and lowers no problem. In other words, if I idle the atv with the charger hooked to the battery, no problem. If I try to run the winch from the power of the atv, it idles good until I try to use the winch. Battery voltage is 12.5 volts so I think the sealed battery is ok. What could cause this? Engine will die instantly if negative cable is disconnected.

    might be to late but, your battery may say 12.5 but it may not hold it under a load, ive had that problem. if not fixed put a load test on the batt.
