I have a Schumacher brand maintainer on the battery for my riding lawnmower. My wife disconnected the clips from the battery to mow the grass. It was still plugged in to the power though for about a week. Now it doesn’t work. I’m getting ready to remove the back plate to look for obvious problems. That’s about all I know to do…..any ideas from ya’ll? Thanks
