Thanks for the wiring diagram. It seems as simple as I thought it could be. It's amazing that ac power passes through the whistle relay all the time but doesn't close it. I will be running a KW and LW phased on this layout. The KW was rebuilt before I bought it and has a stud diode. The LW was also services but does not have a diode so we will have to see how it works.
Does the whistle relay frame make the ground to the chassis or is it a separate wire?
