I have a Henry loader/backhoe on a '59 AC D-14. I installed a gauge to check pressures on the system & found that when the pump is supplying the loader...the gauge reads zero psi, until a lever is moved. When fluid is directed to the 6 stacked control valves for the backhoe...200 psi reads at idle. These are open center valves. Can anyone tell me if this 200 psi reading at idle is normal?...and if it is normal, why does the loader read zero psi at idle?
