Subject: RE: jd sprayer left boom won't lower


nc ks
the three other functions we can manually put power to the solenoids and move the booms. Left boom down won't work even with manual 12v applied so it isn't getting grounding but it isn't as simple as a common ground. Something in the system isn't providing that ground as a safety mechanism possibly. The system also does not like it when we manually apply ground to that solenoid. It is a can-bus system so it kind of loses me. It is the corn post sprayer so we've just been working on it in little spurts here and there. There is a potentiometer of sorts on each boom and we think maybe it is reading wrong or fried and thinking boom is already all the way down.
