I am trying to put up a simple oval with a siding inside using FASTRAK. I have attached a diagram of how I thought it should be done. But I've hit a snag. I am using an MTH insulated section MTH 40-1029 to isolate the section. Underneath it are 3 wires. I felt that in order to isolate the section, one of the wires needs to be removed. But which one? I decided to get a second MTH Connector to just push into a section of the blocked track. Then I wanted to run a wire from the original Power Connector to the proper post on the second one. Which one should it go to- the red or black? A toggle switch, in theory, would turn the power on and off to that section. I don't know if my basic idea here would work or not. And I'm really not sure which wire on the underside to disconnect. Someone once told me the middle rail was negative, and the two outer were positive. Now I hear that's not right, either? If anyone can help me figure this out I'd be much obliged. I've attached a hand drawn schematic of what I had in mind. If I'm totally wrong don't hesitate to say so. Thanks Dave
