Yes it is one of the screw connectors that are green. The offending connection is opposite the side where one connects the headlights and program/run switch. There are four connections on the side with the issue, two that receive power from the track and two that send power to the motors. The problem connection is the one closest to the edge of the board that is connected to the track, call that terminal one. Two, three and four are all fine. What I noticed during the install the wire just floats out even with the screw turned all the way in. I will give the turn it upside down and shake it method a try and report back. Can't hurt, might help.
