I just received the modern version of the Lionel Log Loader 164 (6-12915), but it arrived without the controller. I decided to apply power to the terminals just to confirm the operation before deciding whether or not to return it. When I apply power to the AC then separately to Lights and Drive, both work fine (see photo). When I apply power to AC and Unload, the drive works, but not the unload feature. Question: Is this an electrical problem, or a result of not using the controller?
Thanks,
Michael
