I have a Lionchief+ 82177 New Haven Rectifier Engine Cab#306 that the rear coupler won't open by remote. I tested the coupler by unpluging it from the board and it works if I apply voltage to it. If I plug it into the other coupler socket it works by remote. So the problem must be in the board. Do I need a new board or does anyone know if there is a fix for this.
