I replaced the roll arm, yaw arm and ribbon cable. I checked and double checked all of the alignments. All motors move freely and smoothly with no power applied. I am attaching a video of the gruesome results of my efforts. I'm getting a "Gimbal Motor Overload" message. No indication of which motor. Any ideas or suggestions appreciated. Either for repair ideas or an authorized repair facility, preferably in the Southern New Hampshire area. SOLVED I had the motor shaft that attaches to the camera installed 180 degrees from the correct position.
