The last year or so the machines sticks (electric sticks) have randomly switched up the controls on the right are on the left and the controls on the left are on the right. The last month it has went to rarely working correctly. I had it put in shop hoses, serviced, new iso/trackhoe switch and hydraulic switches hoping it would fix the issue. To better explain. Normally to swing the bucket left or right the LEFT stick does it as everyone knows..now the RIGHT stick will do it instead of curling the bucket. The controls are completely opposite on both control settings.
Does changing the position of the the pattern selector switch have any effect on it ? A new switch is not likely to be defective but, I would not rule out the possibility. Do you have the old one ? I would suspect that there is a problem in the wiring.
Someone said pilot regulator manifold. The right stick performs what the left should on either mode.
An electrical Schematic would show what is what is my first suggestion. Maybe someone out there has one to share or look at. Something is switching power on its own or switching pilot pressure on its own. Simon C
