I bought the engine at York under the impression it was new (or close to new) with the original electronics including tas cruise on it. After getting home and running it, it seemed to have no cruise. I took it apart and found there had been a board swap and it only had the AC/DC commander with out cruise and only two chuffs triggered off of a reed relay under the tender. I’m working through the cruise commander upgrade and trying to get back to four chuffs through the micro switches.
I have upgraded a lot of my older mth engines to ps2/ps3, but have very little experience with the Lionel upgrades. I appreciate your help!
Did the PO retain the TAS motherboard or was that replaced with the DC Commander? How about the sound boards? Are those the original audio and audio power board on a new motherboard or a new ERR Railsounds board? At this point to get cruise you only need an ERR Cruise M.
The TAS motherboard took the chuff switch closures and separated it for both the chuff input and smoke fan. If the TAS motherboard has been replaced you will have to either provide a buffer circuit to drive both or use John's super chuffer which also has that capability.
