Recently acquired this 8050. Used it the other day on the disc and kicked in the FWA a couple times and woked fine. Brother used it the other night and said the FWA wouldn't work and neither would the PD. Checked it out and the fuse for the Auxilliary Hydraulics was blown. Replaced the fuse but it would blow as soon and I'd try to put the PD into high. Took the switch out and I get continuity between all three terminals when I try to engage the high side. Checking the tractor side of the wiring harness I get 12 volts between two terminals and the other terminal appears open. Anyone happen to have a wiring diagram or any input. FWA assist works fine as long we don't engage the PD, as soon as you do the fuse will blow.

Thanks,

Jared

Bad (shorted) coil on PD valve?
