The nephew was playing around on my skid steer. A few days later I went to start it up and realized he had put the key in the run position. The battery light comes on when I go to start it up. It clicks once but it doesn't crank at all.I've tried jumping it, changing the battery, and all the fuses are good but no luck. The lights work, so I know it's getting some power. Has anyone had this issue? Please help. Thanks!
