Problem: Right Motor, Faulty Field Drive (18) You have a problem in the right drive motor field circuit. I would check all of the drive motor to H bridge wiring. The problem could be in the drive motor, wiring from the logic to the H bridge, logic or H bridge. My past experience has usually been a failed H bridge if the wiring and motor checks out. The H bridge is located under the logic card and drive board.
