I have a highflow cat 246 skidsteer serial 00246J55204096.. The accessory hydraulics do not work when hooked into a grapple bucket.. I have power going to the auxiliary buttons on the joy stick and power leaving the joy stick and the buttons work. After that the wires go into a big wiring harness and it's difficult to see where they go. The solinoids are not getting power. I checked fuses and all those were good. Am I missing some trick with the highflow rocker on the upper right hand overhead panel? Should I click that and then try toggles or what?
