drivers for electric over hyd solenoid
September 19, 2019 - 8:42pm

I have a Cat 247B skid steer and the ECM that controls the Aux Hyd has quit according to the Cat dealer.    They want an arm and two legs for a rebuild one.   From looking at the schematic I was wondering why you can by pass the ECM all together.   There is a rotary thumb wheel that controls how fast the HYDs operator.   Here is a break out of the schematic.   I tried to paste a schematic but this system would not let me.

Try adding the schematic again, you can use the IMCE button or upload the image else where and share the link here.

Normally pasting the image as such on the text box also works
