Here's the tale of woe so far. Truck comes to me with left angle only no matter what. Check power all the way to C coil. Replaced both sets of couplers, male and female. Replaced C coil and valve w/ new. Still no right angle. Took all hoses apart to make sure that was not and issue. Checking the go/no go chart in the Meyers shop manual, we are now at cleaning the x-over valve. Undid that and received a face full of oil under pressure. Checked and put it all back together. Same issue. The coupler for the right ram issue under enough pressure that I cannot uncouple it w/o bleeding it off. My next step would be to replace the x-over relief? Any other ideas? By the bye, how strong should the magnetic field be on the outside of the C coil?
