I installed decoders in my PA-1 and E8's (Kato). The PA's are running fine, but the E8's are giving me fits! I can gently push on the top of the plug over the decoder and get them to move, but nothing else seems to help. I taped the plug down, and nada. I taped the back of the decoder and nada. I get the light and everything programs. I set the Mars light and it works fine. Just can't get the stinkin' engines to run without giving them the finger. Should I try some attachment, like Amazing Wire Glue to secure the strips to the decoder? Help please. I have had these locos for nearly ten years, sitting there in the boxes and now, finally can really run them thanks to DCC, and they sit there and flash their Mars lights at me.
