Good morning and happy new year. For Christmas we got one of my sons the above Lionel switcher locomotive. Runs very well. After running “yard operations” for a few days, the rear coupler no longer operates remotely. The sound effect works, just no response or even typical buzz/vibration from the coupler. Front one works fine. Bought it at York from Brady’s Trains - very nice folks by the way - but they are outside Pittsburgh and I am outside DC. Because the locomotive works fine in all other respects and the sound effect for the coupler works, I am thinking this is a simple wiring issue that I can ask a trusted local repairman to handle, but before having him crack something open I wanted to see if some of the folks here thought I was missing something. Thank you in advance.
