I’m brand new to this DCC fun and having issues. I have a LGB Sumpter (21892) mallet with a LGB decoder (no idea what model) in it. I purchased a MRC prodigy elite for my track power. Everything was running fine but I wanted to change the loco address and now nothing. I tried to read the decoder first with the MRC and it would not (tried on program and main line) read back to the MRC. I should have stopped there. But I didn’t. Changed the loco address per MRC instruction, bell on loco sounded, cycled power and now the loco makes white noise and or steam blow off but nothing ells is working. No motion or functions.
Spoke with a few folks that do not have MRC that tried helping. Still nothing.
Any help or direction would be most appreciated.
