I isolated these and tested the locomotive and everything runs fine. I am just not sure if that black wire is critical or not. This was taken from an old starter set S2 Turbine that was defuncted.
If you know the purple and blue go to the headlight isn't that your circuit?
Have you traced the black wire back to where it begins?
