The valve that controls the center section on my boom does not turn when I use the switch in the cab. When the switch is off and I pull the fuse apart it starts to spin or move but the ball doesn't turn. I think I am still getting power to it. Any fixes or time for a new one? Do they still make the ones with the small sq case on the motor? Replaced one the other year and it has a way bigger motor and wouldn't fit so had to turn it sideways and switch it out with another valve.
