Hi,all Merry Chrismass and Happy new years... I have athearn genesis mp15ac UPY1431,..it nice but after try to roll,..that loco roll not smooth like pulse digital and it happen at low speed, i try set CV for speed but it did not effect, and i had give lubricant to gear box,..it still same problem.... Do you all have found this phenomena and how to solve it please? regards
I assume you when you say "pulse digital" that you mean it's surging on a regular frequency. That sounds like a damaged gear, or perhaps debris in the gearbox somewhere, I would disassemble and try manually rolling each truck to see if either one is binding.
This thread may also get some responses in the H0 scale forum. I will copy it there so please keep alert for others answers there.
