Stan and Richie, Thank you for the suggestion as that worked! I have two jumpers going over to Fixed 2 Input and the track on Fixed 2 output. I was able to add the engine and run it.
So does this mean I have a faulty TIU? I will later when I have time try switching it back to see if I can still run it thru Fixed 1 now that the engine has been added and follow-up to confirm if I am successful.
Thank you for helping with this!
Best Regards, Chris
