Recently my JD 6320 began giving message on the instrument panel (unit) digital screen the following message. "Instrument unit not receiving any data. See dealer." When this happens the rpm needle drops. Also it seems as if when this happens the engine will not accelerate. I checked on the grounds and wiring have been checked and have good connection. Has anyone had this issue?
The tractor is a 2004 John Deere 6320 4wd. Here is a link to a video on the tractor of when it happens HELP! John Deere 6320 - YouTube
