    Ok, what am I doing wrong? I just got a couple of Lionel 5166 & 5165 072 used switches. I want to test them on the bench but when I hook them up to the constant voltage pin and a rail nothing happends. I'm using the manual lever to throw the switch.

    well I put a switch on the layout and still nothing. When I take out the constant voltage plug the switch works but since I'm using TMCC it's at 18 volts which is to hight right? it should be around 12 volts. Why is it not working with the constant voltage plug in? I'm using seperate transformer to power the constant voltage plug and yes i did hook up the common to the outside rail.
