Just purchased a 311, From a buddy who was having issues so he bought a new machine. I have experience and resources with these issues in Hitachi and Deere machines just not cat.
First Throttle does not work, manual override button it revs up and down, turn the dial and the dash changes a1 to a10 but does not throttle up.
Second, I don't think the pump is swashing, I can dig with the machine in overide turtle mode, but in normal mode it isn't right. The controller behind the cab (assuming) pump controller green light is on.
Apparently the controller was replaced once worked fine for a while, sent the old controller out for repair says it never worked. previous owner mentioned a calibration when changing the pump controller brings up a code, but doesn't know what, he thinks lightning may have taken them out.
Looks like controller is awake if green light is on, I assume I need sequence for calibration, so I can pull codes and have a starting point.
