No the last time I used it was on my HO track. I put it away for about 4 months and tried it on my O gauge track. Different power supplies obviously but nothing else was different.
Is there any way to test the TIU independently? I do have one of the old traditional 750s controllers but never hooked it up to the tiu if its even possible.
