Wall wart was originally plugged into a power strip with NO Surge protection.
Then I plugged it DIRECTLY into a wall outlet, in 2 separate locations in the apartment. I explained this to LIONEL yesterday. Without ANY further questions to me they issued the R.A.
It was noted earlier in my thread that this same problem was reported by other forumites and Lionel issued them an R A also.
There may be a problem in the Legacy command Cab 1L/Base 1L that is causing this problem. I also gave Lionel the model numbers of my 2 TMCC engines in case they thought the problem was in the engines. Obviously, they did not.
