The original mechanical Hale pressure relief valve with visual pressure relief activation indicator was replaced with a later model Hale control valve, but this one does not have a visual activation indicator. All seems to be working fine, but I cannot tell when the pressure relief is working. I figured that if I T into the line that goes from the pressure relief control valve to the pressure relief valve I could place a pressure switch that would illuminate a lamp if pressure is present activating the relief valve. Since this is a transfer case pto driven midship pump, engine life should be extended by controlling rpms as well as pressure and this light would assist in determining if I have enough pressure/flow at a set rpm. Also would help diagnose faulty or sticky pressure relief valves.
If my concept is correct, what psi should I expect to see in this line when activated? Any suggestions?
Any input would be appreciated.
Thanks
