| I have an old JJG man-lift from the 70’s. All of a sudden it won’t swing to the right. I can still feather the hydraulic speed for the swing but it will only swing to the left no matter which way I push the joystick. Can anyone explain how the electrical system for these proportional hydraulics work and where to start looking? I have a service manual with the electrical schematics so I will try to post pics as well as explanations.
