An update on my machine, I sent some pm's to other members of the TBN and they were very helpful in starting me in the right direction. I also called the service tech at Terex and they were very helpful. I downloaded a service manual and lifted the cab, removed the left and right controls and then removed the floor, all to expose the solenoid block. We had checked all the fuses and relays and everything was in order so I had to figure I had a bad solenoid but I found an even easier fix, some sort of small rodent had chewed completely thru the wire to the solenoid that had stopped working. Anyway now that I traced the wiring of this machine it will be much easier to diagnose in the future. Pretty straight forward layout .
