I purchased a new in the box Lionel culvert Unloader model 6-22975.
I can’t get it to function properly. I run a Legacy 990 system and programmed it to the Unloader. The Unloader responded with the lights on top of the gantry flashing letting me know it connected.
after placing the culvert car in front of the Unloaders electric eye the lights again flash.
the problem is the gantry magnetic crane arm does not move when I rock the boost button forward. I was told this should trigger the crane and make it move. What’s wrong ?
