Well, I think the title is very clear, but I am having a problem with my Athearn Challenger. whenever I just plug in my DCC controller and have my Challenger ready to go, then when I push my throttle up just one notch, it’s gone like a rocket. Input is appreciated.
Thank You,
have you checked the manual or the athearn website?
Your best chance is to use programming on the main. If you get tired of dealing with the MRC decoder, intall a Tsunami Heavy Steam sound decoder.
Detailed instructions on how to do that installation are posted in this forum. Do a search for “wiring harness” . You may have better luck finding “wiring harness” if you use the advanced search.
