wiring help

Hi Vic58

I think you are referring to the Great Northern 4-8-4 steam loco #6-3100.  I suggest you add the engine number in the title of your post since many of us own the engine and may be able to help.  I own this engine and love it.  The sound boards fail, mainly due to the foam that it sits on in the tender breaking down over time such that it eventually touches the metal frame and goes kaput.  Its an easy fix, but owners need to check the foam before starting up the engine.   

I have also added the service document, in case you need it.   Below is the diagram from the Lionel service supplements 1-47.  There are some rudimentary wiring drawings.  Hopefully, someone will chime in with more direct help.   

Hi Brewman,

Thanks for the diagrams, I appreciate the information.

Hello,

After much troubleshooting, I found out the wiring diagram is correct (above) for this newer sound board I was attempting to install in my 6-3100 FARR  steam engine. The problem with the new sound board was that the whistle blows continually with the command control hooked up. When I run the engine without the command control, the sounds operate like they should. I am unsure how to proceed as I enjoy the older engines keeping their original sound systems. My Chicago and Alton steam engine (with the original sound board) works fine with the command control hooked up so it is puzzling to me why this new board will not operate correctly. It is supposed to be a similiar replacement item. I have limited electrical skills so any additional advice is appreciated.
