Hi, this is my first post as a member from over the pond!
I have a US O scale DCC layout that I exhibit in the UK. One of my locomotives is an Atlas "Pennsylvania" RS-1 that had a Lionel TMSS system.
I am part way in the process of converting it for DCC use: have (carefully) removed the TMSS and installed DCC with sound. Electro magnetic couplers have been replaced with standard Kadee 740s. I found the article by Gene Clements (O Scale Trains, Sept/Oct '07 very useful). I am now at the stage of attempting to use the TAS AC version smoke unit.
I am looking for some guidance, if anyone can help. I have searched for posts about this but none seem to match my requirements. The photo below shows the Trains America Studios AC version - I have annotated it to help with replies:
1. There are two red/black connect points A & B - can anyone help as to which would be the track feed and which could be the connect point for a DCC function;
2. The smoke fan motor C seems to have no obvious electrical connection - fan will rotate when wires are applied to the base of the motor (3rd view C).
3. I am trying to work out what "??" connects to?
4. It would also be useful to know if my proposal is feasible? By the way, I have an ESU decoder Tester that I am hoping to use, pre-installation, if that's possible.
Thanks for reading this.
