Hello, I have a 2011 yanmar vio 35-5b mini ex with a thumb on it. I have turned the bolt under the seat to set the pto to double acting as they call it, so that you should be able to run the thumb from the two buttons on the right joystick. However, the thumb now closes with the foot button and opens with the left button on the joystick, the right button on the stick has no operation and does not make any sound to indicate that the pto is engaging. Any ideas why this would be? I would think a bad solenoid would cause both buttons on the joystick not to work? Thanks for the help
