Anyone know the best decoder to use for the newest release Proto GP38-2's? I bought a DH163L0 and installed it. It took the initial address program, but then lost it as soon as I cut power to the track. I put the decoder in a GP7 and an SD60M and it worked fine. I then put the same decoder in another GP38-2 and it acted the same way in the second loco (lost it's program as soon as track power was cut). Best thing I can think is that it's the wrong decoder for the application. Has anyone experienced the same problem or know what the problem is?
