I have a yale picker. It recently stopped moving in any direction. The hydraulics work with no issues. Had a yale technician come and look at it, and he said it was the danaher motion conroller. Replace it with a rebuilt one and has the same issues.When turning the key on steering motor normally turbs on. Now i get no power to the steering motor. The power comes directly from the danajer controller. As soon as i turn key on i get error on motion controller. I have no idea what this means. Has anyone else had anything like this happen?
