Re: Cat 120G Grader

Those wires go down to the fuse box located directly underneath the driver compartment on the right hand side, and that air solenoid valve for the centershift lock is fused.  The fuse box is situated above the articulation valves (depending on year).

Cat 120G Grader

I have a 87 Cat 120G grader. The centershift lock will not work. I have air to the solenoid below the lock control valve but the soleniod has no power to it. The wires go into a loom so I cant trace them down and cant find any bad fuses. Does anyone have any ideals on where the go? or what could be stopping the power to it?

 

Thanks

Scott
