Since you said that you swapped the wires to the Tortoise 2 and 3 pins and you got the same result tells me that something is wired wrong.? You can troubleshooting with your DCC power, but it might be easier to disconnect your booster and hook up a digital multimeter set to ohms.? Hook one end to a rail and the other end to your frog.? As you switch your Tortoise, you should expect to get zero ohms as appropriate for the alignment of your points.
