Hi all, I'am making a H-bridge for my 300w scooter motor. I connect the H-bridge to an arduino for control. I can make the motor run forward without problem, but when i try to run it backward the motor doesnt run. I try to measure the voltage of the output 20v forward and -20v backward but the motor just cant run backward. If anyone can help plz thank you!!! Here is the sch of the H-bridge
