New to this forum, I am having trouble with my 331 hydraulics. Have no boom down pressure unless I move the joystick slightly to the swing left position then it slowly creeps down. I swapped the 2 outlet hose for the boom on the main control valve to the dipper arm valve and boom works great. Problem went to the dipper arm. Then I switched pattern changer to cat controls and the problem went to the other joystick. I cannot seem to find any hydraulic schematics to download. Any advice here would be great
