My Suzuki Boulevard C90 battery went dead on 2 battery out charged it put it back in like a good power turn turn turned would not start and the power would stay on after I turn the key to off and pull it out. Had to disconnect the battery. I tried it again the text day and the bike started and seemed fine till I tuned the key off then bike stayed running I hit the kill switch and it still ran I had to disconnect the battery to shut it off. Any ideals?
