I have been having a few electrical problems with the layout and have done some modification to the way i had the layout wired.
Some of the rework is to update how i am doing my wiring.
1.had all dropper (wires from track to the main bus wire) the same colours (Red and Black) and started changing this only after a few months of starting the layout but never when back to do the rework.
Main line droppers :Red and Black.
Yard droppers :White and Blue.
Servos droppers :Yellow and Orange.
All the Yard and Servo droppers go to plug to make it easier to drop out sections to find a fault.
this is one of the Connection Boards I had made up, This one is for the servo feed cables. Since the cables do a loop it is so that both ends are connected to a single cable to the Boosters.
The Main Line is split in to 4 sections 2 upper deck 2 lower deck. the Yard feeds do the same thing.
