VL big boy 4005 6-11436 main smoke stack issue

the 1st smoke stack of the dual units stopped smoking and puffing but the 2nd smoke unit works fine. tried an experiment swapped the plug from smoke 2 unit to smoke one unit and the 1st smoke unit works while the second unit not working with the smoke 1 units connector plugged into the 2nd unit. the whistle smoke and blow down smoke units work fine. so is the rcmc at fault or is there something else at play that I'm not aware of?  ironically no cab light blinks associated with this issue!

seeing all the smoke units plug into the rcmc board I would think the one circuit for smoke unit one on rcmc has an issue? any help would be appreciated on diagnosing and the cure. I prefer not to send to lionel as had bad experience with them when under warranty so please let this not turn into a flame of responses as I really could use help getting this issue resolved.
