I looked everywhere under and traced the electric harness to the battery but saw nothing... Except that the snake is still there.
Here are some pictures:
I'm stumped. There are no notes as to where it is. I will keep good notes on any modifications I do. Lesson learned.
Nicholas, I hope you don't mind that I "LOL'd" a little bit... since the kill switch has been right there in front of you the whole time!
One thing to add... sometimes the little clip gets partially broken and doesn't pull the "pin" out far enough to fully disengage the switch. You could always manually pull the switch all the way out.
Or, the connectors in the wiring harness have gotten pulled apart (these would be behind the assembly). Some systems require an open switch to allow the engine to start, some systems require a closed switch - I'm not sure which one you have - but if the wires were pulled apart and you had a no start, then yours would obviously require a closed switch to operate. I'm pretty sure all older engines just grounded when the switch was pulled to kill the engine. With a 2007, there is going to be a computer involved so I'm not positive.
On some motors, you can test to see if the kill switch is working by trying to start the engine with it disconnected - it will sound an alarm.
