    I recently purchased an SDN144A0 sound decoder for my Atlas N scale Dash 8 locomotive. The problem isn't with the functions of the sound, thought it is not that loud in comparison with some of the other brands. That is besides the point. The issue I am having is there is no movement. The motor will spin and the wheel will move. I ran it many times pre decoder instillation. Now nothing but sound and lights. What should I do?

    You said motor turns & wheels move? Was this before you installed the decoder ?
    It sounds like you may have lost the drive transistors on the decoder.
    I would see if you can do a decoder reset to see if it will come back to life. After that , I guess that I would make good the decoder return policy that Digatrax has.

    Well, I went back and realize that I didn't place the tabs through the slots. This was the problem.
