GGG posted:No the switch position will not damage anything. Sure you can't see the connector that plugs into the drawbar without removing anything?
I am also confused that it works on your test track. I am not following that part of this. IF it runs on a small test track, but not your layout, I start to think you have a DCS signal issue on your main layout. G
Tried the DCS/DCC switch in both positions. Didn't fix things.
Removed the drawbar so that I could check that the the female pins were seated in the conncector. All looked fine. Put things back together. No change.
The test loop with a Rev. L TIU, powered by a PW KW (fused and TVS for protection) , 18V to Atlas track is the only place I have tried it (no permanent layout... yet).
So off to MTH it went for warranty repairs. I was told 2 to 4 weeks.
Will keep you posted.
