Since I was going to post anyway, I thought I'd share what happened to me this morning while trying to hook up my Lionel command base to my MTH DCS which I had done years ago and it all worked fine. I was getting ready to ask for help and took one last look at why nothing was working on TMCC but everything else was fine.
Just before posting I looked for the power on light for the command base. Well, as you can probably guess by now, it wasn't. Yea...It doesn't work unless you have the power pack plugged in. Took about 10 minutes to find it and everything works great!
Happy Friday. You have to have a sense of humor!
