If not both turn forward, but the following situations occur, you need to readjust the wiring of the two motors.
• If both motors turn backward at the same time (left motor turns clockwise, right motor turns counterclockwise),
swap the wiring of the left and right motors at the same time, OA(A) and OB(A) swap, OA(B) and OB(B) swap.
• If the left motor turns backward (clockwise rotation), exchange the wiring of OA(B) and OB(B) of the left motor.
• If the right motor turns backward (counterclockwise rotation), swap the wiring of OA(A) and OB(A) of the right
motor.
