Changing the Cabin Master Pressure Regulator on the first B-47 jet bomber I was crew chief on..S/N 51-2338 back in 1956. This unit is "buried" in a compartment below the floor level in the cockpit behind the co-pilot's seat. You have to lay on your stomach curled around the seat and work through an access hole about 12 X 14 inches and 16 inches deep. The regulator unit is secured to the pressure bulkhead by a dozen Phillips head capscrews in a circular pattern about 10 inches in diameter. You have to use a magnetic tool to remove and replace these capscrews because you cannot reach them at all with your hands. You loosen and tighten them with a socket Phillips screwdriver, 12 inch long 1/4inch drive extension and ratchet. Of course you have a gasket to replace and keep in position aligned with the holes perfectly too as you do this "little detail". Thank God I was young and kinda skinny in those days, I doubt if I could do it now..(weigh about 60 lbs. more and can't see without glasses).

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
