I have a pmdx-126 BOB connected to an ESS. Apparently, output pins 2 & 3 from port 1 stopped working. I checked wires, motor and driver by switching everything out and all were working properly. I moved the output to the motor to J5 pins A & B on the BOB and port 2 pins 1 & 14 on the ESS and the motor moves now, but only in one direction.
