Recently I got an Athearn MN Northstar HO scale F59PHI, and I just went and installed DCC on it so I could put it on my layout. Today I put it on, excited to run it. I used address 3 (which the decoder manual said it was pre-programmed to), and could turn the headlight on and off, but the engine wouldn't move. I tried it on a DC test track and it worked forwards but would not move in reverse. The loco worked perfectly before I added the DCC decoder. My system is Bachmann EZ-Command and the decoder is a Digitrax DH163D. Any ideas as to why this isn't working? I tried switching the decoder address, and the loco recognized the new address, but still would not move.
