Hello all, I'm having a little problem with my dcc++ system. I'm running an Arduino 2560 mega and an Arduino motor shield, I am using a 13.8v power supply and I have successfully got the dcc++ controller to communicate with the Arduino but when I flip the power on there is nothing on the mainline. My DCC sound locomotive remains still and silent and when I place a DC locomotive on the track, it remains stationary as well. I have checked and I have continuity between the rails and the motor A hookups, I have also checked to make sure that I have voltage on the track with my multimeter set to AC, what am I missing here? EDIT: It occurred to me that I should check the other motor connections and sure enough I found 16 volts on motor connection B, suddenly now everything works correctly.
