Is your power steering unit the one made in Turkey? It sounds like the steering cylinder you have is a slave cylinder with the controls in the base. If so, I can help you. From what you have written, I am almost sure that the cylinder controller is in need of adjustment. Call me and I can walk you through it.
Also, I have received several emails from the fellow who makes those steering units in Turkey. In fact, he called me one morning. So, if we don"t have any luck getting your unit to work, then I will try sending him an email for help. He is a real nice fellow, but a bit hard to understand. I am sure that he would be willing to help.
Several days ago, I received an email ad from his company, so I know they are still in business.
Anyway, I will do what I can to help you.
Best Wishes, Roland Jackson
