On my unit, when facing the bobcat (entering it) there is an electronic brain to the left of the seat, and there are 5 lights.
One for each safety function.
I dont have a good photo of it online anywhere.
Mine is a 1999 model.
Did you try energizing the starter directly from the battery?
If you put 12v to the starter lug, it should start turning the unit over immediately. (the red circle in the photo)
Also, when you turn the key on, does the fuel shut-off disengage? (the blue circle in the photo)
