update:
no loose fittings, linkages are tight, all quick connects are tight, piston(boom cylinder) moves fine with air only
what i've found is that when the lever is actuated(pushes down) nothing happens, it just releases the pressure, does this mean something is wrong in the "switch" it acts as if its not activating when pressed?
it looked as if there were just 2 allen bolts holding down the bracket around where the switch is, i didn't take them off wanted to check here first and see if this helps anyone
thanks again......jp
Hmmm... from your description of symptoms - sounds like a valve body issue.
I'd go to JDPart's (if you don't already have the Technical Repair manual) and look for a detailed printout of the 447 valve body to help clarify the likely next step in the troubleshooting/repair sequence.
