Friend of has a 660 grizzly, 2005. New battery drains to nothing as it’s being used. Going to order both a stator and rectifier and just replace both. As his machine isn’t here, I can’t go over it much and I’m not sure where the rectifier even is on his 660. So where is it and also the side case cover that holds the stator, does that require a gasket or some sort of RTV to seal it back up. Tks for any help on this.
