I may or may not have posted about this before. My local club has a pair of MTH PS2 Montour SW9s, product 30-2327-1. A while back, both engine started operating erratically. One of the two has sounds and lights, but does not respond to a DCS track signal or get found by the remote. Sometimes, when it is placed on a track, the sound and lights turn on, other times it remains dark. The other SW9, after running on my home layout for a bit, lost sound totally, no emissions whatsoever. The lights still worked, though. It ran fine for a while like that, but after a while it started randomly stalling out when doing switching. Now, whenever I try to run it, it needs a shove to get going and to prevent it from stalling. I haven't tried to run the engine in some weeks, so it might have quit moving for good.
Any idea what the problem(s) is/are? Are they fixable?
All comments are appreciated.
If you need them, there are several videos of these engines running on my Youtube channel.
