hello friends got an issue with a S45 that has me stumped at the moment. it wont steer left or right unless i'm moving forward or reverse ,either way doesn't matter, and booming down all at the same time. that is the only way it will steer or that the way i got it loaded at job site to bring it in lol..ive checked voltages at the valve and getting 10v left and right not 12v. ive checked service manual for maybe a priority valve of some type in function manifold but no luck or i'm looking it maybe..spent the better part of the day on job site troubleshooting and could've overlooked it yesterday evening..any help would be appreciated..thanks in advance..and thanks for the forum it has been a lifesaver multiple times for me definitely

You can remove the hoses at a steering cylinder and stick a pressure gauge in it. You need to know what relief pressure you have to get you going in the right direction.
