I have a Lionel Virginian 6-28333. It has the modular boards with a smoke regulator.
I've had the shell off and checked everything I can think of twice. Smoke motor works, new Lionel rope wick and even swapped out the R4LC with no results.
The smoke unit will function but will get "wonky" at times. Sometimes a bit too much smoke and mostly will just cease to operate. Sometimes a reset will cause it to come back on.
Might it be the smoke regulator? Can this part act up like this before complete failure or is something else amiss?
Thanks Again Guys
Appreciate the help
Dave
