No, it ran fine for a while after I bought it.
I will check to see if something is touching the top of the decoder (I assume you mean something metal that is causing the short?) but what is a decoder card and how do I know if it's seated correctly?
The loco ran fine for quite a while but then I noticed it running a little "jerky". This was easy to see because it was consisted with another engine which ran fine. I speed matched the two engines pretty well and they ran great together for a while.
Then the loco would not respond to throttle (the sound would but it wouldn't move). Later when I turned on the layout it would jerk forward a couple of inches, stop (this is when I noticed the display showing it was drawing way more than it did) then the dcc system would short.
The engine in question is a Paragon 2 and it was consisted with a Paragon 3 but I can't think that is a problem.
Thanks for the advise, please advise about the decoder card.
