I have a foot control t190 that is now showing an ACD light on the left panel. It now has no auxiliary hydraulics. It is also showing no codes. The book says that this is an output A problem, but looking at the hydraulic schematic, I can't determine which solenoid is the A side on the auxiliary spool. I'm assuming that the problem is either with the solenoid or somewhere between there and the switch. Anyone have any experience with this problem? Thanks
