On a previous thread, I posted my problem...that an entire section of track has power UNTIL an electrified car, either an engine or car with a light) enters. I originally suspected a new Ross switch which replaced an old Lionel #022, but that's not the case since I removed the new switch and the problem is still there. I haven't gone so far as to put the old Lionel switch back into place to see if the problem goes away but I might, since this NEVER happened when the old switch was there.
So I've attached a revised and simplified diagram focusing on the problem. I have the same amount of power set by the transformer showing on my volt meter UNTIL I place an electrified car onto that section. At that point, the power in the section (the black track on the attached diagram) goes dead. It doesn't matter if I roll the car into that section from any direction, or just place it there by hand. The second I do - POOF, no power.
It's also important to note, I think, that the black section highlighted is not an isolated block. It's electrically connected to the red section preceding it. (The blue and green tracks ARE separately isolated blocks.) Within the black section I have two drops 6' apart - both for the center rail and the common, one inside the reversing loop, and another leading to it.
Anyone with a solution has my undying gratitude (and envy for your knowledge). I know I'm going to lose sleep over this one. Please help!
