After my basement fiasco its time to get the switches going again. Only this time, I want to keep the serial port of the Command Base open, so instead of using a IC Controls ASC-3000, I want to get previously owned Lionel SC-2 going. It arrived with the trace to the power terminal cut.  I know this breaks the connection between the rear power plug in and the terminal post. I have the pdf manual and read it up again. I remember at one time I had a piece of copper wire restoring the connection, and now that wire is not there, and whatever I did, the unit was working. I tried searching the forum but my search skills must be lacking.

Why did we cut it? From the manual, seems easy, either power by AC wall wart, or track, but not both. Idiot protection???

My intent is to use only with switches, K-Line SuperSnap that only require a momentary short to ground just like Lionel O gauge switches. It

I see my problem. I used "SC-2 cut trace" should have used "SC-2 trace".

More importantly, in my post above, there is a mistake. The cut trace is NOT to break power from the rear plug, it is to disconnect 'Common' from the center of the first terminal block. This makes much more sense as to why one would want to cut the trace.

I edited the post with strike through for the wrong info.

Note that the SC-2 could be powered two ways.  There was a provided wall wart, that plugged into the SC-2, or you could use track power/aux power.  (The cut traces).   You can cut the traces, as long as you understand, the operational power to the SC-2, is via the Wall wart.   SC-2 also operated the same as an engine, gaining TMCC signal from the nearest outside rail.  There was discussion about the position of the SC-2, near rails, so that TMCC signal was available.
