"This is where it gets funny. I've managed to get two of the turnouts working...If I attach a third turnout and then try to test the DCC, it senses a short and doesn't "boot" up. Get this. Off the layout the third turnout works fine. No shorts, and if I clip it to my Power Cab it boots up no problem. However, place it back in the yard ladder I get the same issues." OK, so you have two turnouts on the layout, wired to the busses, and you can apply track power and throw the turnouts with no short, right? "Its when I get to the third turnout out or anything beyond that circled in red do I have problems...Off the layout, and hooked up to the DCC or tested with a Voltmeter, no issues. Even if I only hook it up to only the two green turnouts it also stops working." So, if you place the 3rd turnout on the layout using railjoiners to connect to one of the other, working turnouts, and do not attach any feeders, you get a short? If that is what you are saying, then my first test would be to put the turnout in place against the working one with no rail joiners. Use wires with alligator clips to jump power as the rail joiners would. See which rail, or both, causes a short. Then connect the 3rd turnout to the buss and power up while still in place with no rail joiners. Obviously, make sure you have the correct polarity buss wires attached to the rails. Use a 16 volt bulb to check polarity in the various pieces of rail. Given that you get a short when connecting the 3rd turnout with rail joiners and no attachment to feeders, if you can connect feeders and do not get a short while in place without joiners, use the lamp to test polarity of the adjacent turnout rails. If the bulb lights when leads are on the opposite rails of adjacent turnouts, the rail joiners cannot cause a short. You'll need to start eliminating possible causes and see whats left I'm afraid.
