My wife's Z370 has something wierd going on with the electric strater and I need help. Turn key to start engine, starter engages, engine starts, starter disengages enough that the teeth aren't touching but keeps on spinning. I can take the key out, hit the kill switch engine goes off but starter keeps spinning until I disconnect the battery. I would appriciate any help becuase I don't even know were to start on this one. Sled does start and run fine with the pull starter, but she'll use elctric start to give the kids rides around the yard when I'm not here.... thanks
