What sort of power to track do you have as now about 6 diffrent types? Is the tower the one with two light a tower witha button on the side with a winder clock work nob C275? If it is I have one. (The instuction say connect the two wire leads to the power pack, one lead to each terminal. Providing the power is turned on, one of the lights on the arm of the buildingwill light up. ) one wire is green one is black. so im guessing the same one. if you need to know how it works come back to me Hope this helps.
