jim you got a picture of that switch ?
where is the switch mounted, and what does it do ? according to hwh info
i worked around industrial hydraulics and machinery controls for my CNC career
50 PSI is like air pressure level, way low for hydraulics
could this be low pressure cut off, if you dont have a minimum of 50 PSI the system defaults to NON-OP and won't try to activate the jacks or slides ?
way to low for an over pressure alarm on hydraulics
pull the wires off the switch
read continuity of the switch, is it open or closed with the system off
where is it leaking ? at the threads where it screws in ?
might just be and 'O ring' seal
