Last week I received a brand new Legacy USRA 2-6-6-2, Lionel number 6-85184. I am using a TMCC Base and controller 6-12911 powered by an MTH Z4000 set at 15 to 16 volts. The only problem I have found is the rear electro-coupler doesn't open when I press the button on the controller. I can hear the solenoid energize, and if I put my finger against the coupler, I can feel a slight vibration, but the coupler doesn't try to open. I compared it to my only other Legacy engine, a GP7, and the solenoid sound and vibration are about the same. The GP7 couplers operate as they should.
Is there something I can look for that may be causing the couper to bind or not operate? I don't see an obvious burr or other deformity. I don't plan to do any switching with this engine, so I probably won't use the feature much, but since it is new, it should work. Thank you for any suggestions.
