    Hints...
    4...has nothing to do with the wiring..
    5 and 6 have something to do with the engine harness
    7...doesn't have anything to do with anything...

    No...but the fuel solenoid is what is eventually turning off the engine when the power is turned off...

    A few years back, I worked a Walker that would run on a few seconds longer that it should. The machine was only used in the winter, it had a snow thrower attachment. When not used, it was stored in a building that contained all the fert. and chemicals. Some how the key switch got contaminated and bridged the connections in the switch.

    In this case, and I'm only guessing, there are crossed wires
    or a bad wire plugs, Yes ?
