Missouri | Just for curiosity sake take a look at the the pump switch. That switch gets replaced with an ag leader switch when you put the system in. The switch is longer than the original deere switch. I had a 4630 that the wire from the pump switch on the switch itself was rubbing a bracket that is attached to the hydrostat. It would lose communication with VIM and L2 plus give a GPS signal lost. We chased it for over a year trying to figure out what it was and we finally figured out it was doing it every time we moved the stick. This may not be what it is but open up the armrest and take a peek. | |
