They key switch is the separator. Either off or ground or platform. All connections between the two are made in the ground control box cabinet terminal strip then they feed out to engine and manifold. Best thing to do is down load the services manual and print the schematic out land scape style. Get a ruler a razor blade and some tape and put it all together. If your not familiar with the wiring this makes it a lot easier to follow and trace out circuits. Or you can have it printed out like we do at a sign shop that has the capability to print large area pieces. Over the years and owner after owner mechanic after mechanic and diyer after diyer things can sometimes get out of hand in the wiring repair department.
