BradK posted:There appears to be a lot of possible variables here. If I am following everything properly, the Legacy System has never worked properly for you. If this is the case, I would set up a test circle/track with its own power supply and test the legacy system there. If there is still an issue, I would test another train just to confirm and a different power source. If there is still an issue, then it would appear to be a problem with Legacy unit.
But if the test circle unit works, I would retest using the primary power outlet used for your layout.
If still good, I would attempt to get a power feed from your primary transformer.
If still good, I would attempt to hook up the 'Y-Cable' only.
If still good, I would attempt to hook up the TMCC Base
With this approach, it will help you identify what works and what cause the system to fail.
Hopefully it turns out to be something simple like a bad connection or "Y-Cable", instead of something with your layout since it looks like you have a complex layout. But since it worked with your TMCC base, this seams odd.
Two additional test:
If you just hook up the Legacy Base - Leaving the "Y-Cable" and TMCC base disconnected, does that make any difference.
Also you may want to try hooking the TMCC-Base up only - to see if your original configuration still works.
Just my two cents.
Sorry Brad, somehow I missed your post in the flood of replies. I like your scientific approach here.
Let's consider the test circle passed. As I just mentioned in my reply to Dale, Matt did that test and said it was good. TrainroomGary suggested that I send it to Lionel for repair, but I'm skeptical about that, as I suspect that they too would say it's fine. This has happened with a number of my engines as well, simple track test out fine, my layout crap.
I have never tried Legacy base only. That's an easy one, yank the cable and power up. Going back to TMCC has always worked, that's easy too.
