Light and smoke problem?

I have a Lionel SP Atlantic engine made about 2000. The problem I have is when I turn on the light the smoke unit goes on. I can not turn it off unless I shut off the light with the Legacy controller. I turned off smoke switch underneath engine and it still goes on with the light. I hit the 8 button and it won’t shut it off. I reprogrammed it and still the same thing. It doesn’t impair the operation just can’t shut off the smoke and have the light on at the same time. Any suggestions?

Laz, Is this a new addition to the roster or is this a new problem to the old roster? Have you checked the Lionel site for the wiring schematics? If a new addition this would allow you to see if something was mis-wired from the factory.

Took a quick peek and they should be on an entirely different circuit from each other:

I opened it up and made sure boards were press down and noticed a pinched wire. Put back together and now it works. Go figure, either a pinched wire or loose board? Just figured I let youz now.
