Aaron just came up and woke me. Asked why the Toro was running! WTF?????? Sure enough, it sat out there idling. All I can figure is the showers shorted the switch and started it up. This is the Mitsubishi K3D. I had to reach down and hold the kill solenoid in to kill it. Got some wrenches out and unhooked the battery. But, still need to figure out how it could have energized the fuel pump and starter. Had to be the ignition switch.
