eroclb: PLEASE get a manual before you operate this very much!!!! The knob your twisting on under the seat HAS NOTHING to do with the hydraulic pressure. It is the rate of drop valve for the three point lift. IF you have tightened it in then you may have damaged the valve.

While I love straightening sheet metal, cleaning, and painting old tractors, I use every excuse to avoid working on the on the electrics. I find the whole process sheer mystery. I have picked up and attempted to read every auto and farm electrics book with no improvement in the situation. They all seem to start with a chapter entitled "Theory of Electricity". After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
