Have a 2016 AXYS with electric start and PIDD. Last year put an earth X battery in it and have had zero issues. However, they say the battery can be left in the sled. But after just a few months, it had drained the battery to a point it wouldn't turn over. I took the battery out and charged it and has maintained a perfect charge for three months now. Supposedly Polaris has a bulletin out saying the PIDD does in fact drain batteries. Any one have info on this?
