we have a 664 orator sprayer and when we went to use it today,we have a problem. we think it might be the ground speed sensor because there is power going to it but it is not sending info back to the speed display on the post. is there any way to troubleshoot the problem?

that speed display is only really there from when the cab was on the combine
is the speed working on your rate control meaning raven ? if not calibration on that maybe outta wack that's radar for speed on that isn't it it was on my 854

I had to replace the radar unit on my 664, it would not read smooth ground, there is a plug connector in the cable under floor mat on right side of cab you could check that first.

my neighbor had his cable rub a bare spot, check that, he patched it,works fine.
