I have a question that maybe someone can help me with. I have an MTH ho SD70ace DCC and sound engine. I had it worked on my a local hobby shop and they messed the CVs up pretty bad. I’m not really sure why they did it. they claim they didn’t do anything. I need to reset my engine back to factory but it doesn’t seem to want to reset when i try. I’m using a NCE Power cab. Any help on this would bge great thanks.
Using programming on the main, select loco 55 and program a value of CV55=55.
Make sure no other MTH locos or a loco with ID 55 are on the track.
