I have been chasing a problem with the boom swing button not working on a New Holland EH45. (relabeled Kobelco) I narrowed it down to the 2 lockout solenoids by the selector valve staying energized. I have seen some info about the sequence box that controls them. Is there any way to test this thing? Does the sequence box do anything else other than lockout the boom swing? If so, is there any reason that I can't just unplug the 2 solenoid valves?
