Pat,
Thanks for your response. That is helpful. I do think I have it wired so the smoke unit was drawing track power. Just for clarification, the R! and R2 on the board would be the resistors, correct?
Would you be able to tell me where I could pick up the type of resistor you are referring to. I think I could isolate and by pass the resistors and replace with the TMCC resistor as you suggest.
