I am working on a 420D sn# cat0420DPBLN11615. The switch was broken on the dash, I replaced the switch and still had nothing. Traced wires up loader frame and found two broken wires fixed them. I now have power to the front but no fluid flow. I have tried to trace the wires from the switch to the pump but have been unsuccessful. Does anyone know which solenoid on the pump controls this function? Or is there something else I may be over looking. Thank you for your help.
