Hello all you problem solvers
I have a MTH SD40-2 PS-2 that is not being nice. It is the center locomotive in a three unit consist. Started out as a minor glitch of not always receiving a command, now when I start up the consist it just wants to move, the other units all behave nicely sitting there at idle waiting for the next command. Tried running it by itself, as soon as the power turns on it moves with no sound or smoke it is not in conventional because it will stop then reverse itself then again stop and go the other way keeps doing this. I tried start button but that does not help.
Item # 20-2669-1
Thank you
