Modern 445 switch tower ( Lionel 6-12917)

Thank you very much for the assistance, Larry and Bob. The exploded view provided by Larry indicates the second AC Power clip is not connected to anything. I have printed out the exploded view to file with the operating instructions. Also, I was successful in wiring the lights to operate with an accessory transformer and operate the Action function using a isolated track.

Thanks again, Swede

Could you post  photos of the markings and the underside wiring connections of your unit. It will help in getting answers to your questions. Thanks.

 Bought used 6-12917 switch tower. Has 4 ea. connector clips, all in a line, titled AC Power, AC power, Action, and Light. A wiring schematic molded into the base of the unit shows connections to be made between the second AC Power clip, Action, and Light. When bench testing the unit, I had to connect power to the first AC Power clip to get Action and Light to operate. I took the base off the switch tower and discovered o the second there was no internal wire connected to the second AC power clip. I have searched the internet for a photo or schematic showing the internal connections but have not located either. Would you happen to have such a schematic? If not, would one of you be so helpful as to post a  photo that shows where the second AC Power connects internally? I would be most appreciative.

A second question regarding this unit if I might. After getting the internal wiring straightened out, do you know if it is possible to make external connections to operate the light off a accessory transformer and separately operate the Action function using an isolated track?

Many thanks, Swede
