I just put my new No. 2032040 Rio Grande Lionchief Plus2 docksider on the tracks. Everything appears to work fine, except the rear electrocoupler doesn't work, or at least is very intermittent. I'm using the LC app on my Apple mobile phone. If I hold my finger gently against the coupler, I can feel a little momentary bump. It seems the signal is being sent, but the coupler may not open. Sometimes it does, usually not. It's like something is binding inside the coupler "arm" (the part that opens).
The uncoupling sound works fine. The front electocoupler works fine. Are there any "quick fixes" anyone knows for inoperative electocouplers with this kind of issue, or is this something that has to be returned to the dealer (ugh!)?
