I had a similar thing happen to me a couple of weeks ago, except the problem occured during start rather than shut down.
The bike had started normally when I left my house. I stopped about 15 minutes later for gas. Got ready to go...ignition on, sidestand down (trans. in neutral), push the start button, and although the engine does not start, the starter just keeps cranking. At first I thought it was my imagination. Turned the ignition off...starter still cranks. Hit the kill switch...starter still cranks!
I think I turned the ignition on and off again, and may have partially removed the key...I don't remember exactly. At any rate, the cranking stopped, and when I turned the ignition on and hit the start button again, everything was normal.
As it happened, I was on my way to the dealer for the 7.0 upgrade, and told him about the problem as soon as I arrived. He was stumped, and the computer didn't show any fault codes. I'm no electronics wizard, but I don't understand how the starter could crank with both the ignition and kill switch off, especially since under normal conditions, the starter won't crank with the kill switch in the off position.
It hasn't happened since and I was beginning to think I was crazy. I would really appreciate any insight this group can offer.
