We have this 2010 Polaris AWD 500 HO, and thought at first that the battery was just low, so we put it on the charger. It might start the next day, run fine while still connected to the charger, but after disconnecting the charger, it starts to sputter, and will die. If we disconnect the cables from the battery, connect the charger directly to the cables, turn it on, start the 500, it starts and idles fine. But when we turn the charger off, the 500 immediately dies. What should we be looking for electrically that is keeping the battery from being charged, or isn't sending juice to the battery?
