Hello. Recently purchased the EZ Command Plus controller used (warranty is up). After reviewing the contents of this string, I have concluded that I seem to be having the same issue where as when I power the controller with the wall outlet the buttons light up fine, however, when I connect it to the track, the track has no power. To test it, I used a friend's EZ command controller (the standard version), used the same power cable (controller to track) and the same locomotive. His controller works just fine. Any suggestions as to what I may be able to do to resolve this issue?
