Kewatin...thanks for the reply and advice. It is DCC ( MRC Prodigy). Ill check to see if its the wires from the tender to the Loco. Ive tried a CV factory reset and also CV2 voltage reset but still nothing. I am aware of the warranty and the possibility of sending it in for service, but I would rather see if I can trouble shoot it 1st. Its my sons xmas present and I would like not to have to send it in not knowing the turn around time for a return. I do work just outside of Philly, so bringing it there in person is an option.
Since Im at work right now I cant check to see if resetting CV8 works or not. What does changing CV8 represent?

Hoping someone has a solution for the loco not moving. All of the functions work ( sound, lights, horn etc) however the loco will not move forward or reverse. I have tried re programming, putting it on different tracks. Our other locos work fine so I know its not an issue with tracks or the layout itself. The Loco is fairly new, only a couple months old and I have had no issues with it so far. Problem started yesterday while it was running and it came time to shut it down, there was NO response from the throttle. Thanks in advance for any help.
