Hi there fellow Harley riders, I am brand new to this forum. I have a 1988 sportster 1200 and a week after I got it this happened!! The starting system worked normally by turning the on/off switch to run and the key to on and then pushing the start button. Just like it's designed well now all the sudden the bike starts when I turn the key on. I think the starter is still spinning when it's running so I turned it off immediately. The first time it happened it startled me so bad I almost dropped the bike over on me!! I am capable of figuring it out but just need a wiring diagram or some good advice. I will appreciate either. Thanks a bunch!
