Guess I should have labeled it "Hey Bill". A truck came in (57 3100 IIRC) that belonged to a lawn/tree service and had this on it. Before swapping in a V8 and all the usual goodies we plugged everything in the shop into it and it would run drill motors, skill saws, etc. and everything that didn't start with a capacitor. As you can see the wire out has a black, white, and green just like house wiring. I wonder what is inside it since it's all inside the generator case and the twin plug receptacle.
