here's the senerio. I have a loop of fastrack withal the bus bars removed so that I have an Isolated outside rail. the loop is cut up in 3 blocks for 3 3 aspect signalsi had it working fine with relays but changed the loop configuration added a second loop with 2 switches between them and also added another switch that brings the track up from another level. I'll add a picture to show. well with the switches in place the outside rail is no longer isolated. so I opened up the switch and removed the buss bar in the switch(manual switch) but it is still getting power somehow. I guessing from the inner loop that has it's bus bars still in place. is there something I am missing inside of the switch that's still making the connection? the blue loop is isolated the red is the switches and the non colored track isn't isolated. in the switch there were 3 bus bars
