Hi there, I was hoping somebody out there may have had this problem and be able to offer some advice.
I have an IH 674 and the power steering has stopped working. I have seen it suggested on several forums that you should check to see if it works when the auxiliary circuit is activated. I have tried this and sure enough, as soon as I put the auxiliary spool valve into lift, the power steering starts working like normal. Dose anybody know what fault this indicates? All the other hydraulic systems are working ok. I know that I should really be doing pressure and flow tests, but I don't have access to any test equipment.
