Just purchased and received the Lionel TMCC S-1 electric locomotive (18351), and on "one" of my Lionel Fastrack switches it makes a spark on the track, causes the fuse to trip on the power brick and stops.
However, it seems fine on the other switches.
Note, that the two switches are two different sizes (degrees).
Any suggestions?
Now this same switch sometimes will cause a spark in conventional mode, but never trips the fuse, and has never sparked in Legacy or TMCC mode.
Thus, I feel it is something with the loco.
