3. The monitor is set on the incorrect ground-speed setting.
Solution: With the load displayed, press the DIST key to display
“SPD=WHL or TRK or RAD or GPS/WHL or GPS/TRK or
GPS/RAD”. Use the bottom-right UP or DOWN ARROW key to set
this to the correct speed setting. If you have set loads to the incorrect
ground-speed setting, you can change the loads to the correct speed
setting, and the monitor will automatically correct acres and distance
(will not work if the correct speed setting was a GPS speed setting)..
4. Distance and acre counting are not activated because the area count light
is on (you will see mph).
Solution: Make sure the area count switch is in the up position (if it is in
the down position, the area count light will always be on), and the stop
height number is set low enough so that when you lower the combine
head, the area count light turns off. Refer to the troubleshooting
instructions for “Area Count Light Always On”.
5. The Ground Speed Sensor has no signal or the signal is erratic.
Solution: If the yield monitor is using the combine ground-speed sensor,
read the installation instructions and make sure you are connected to the
correct speed sensor on the combine transmission (particularly on Deere
9x00 combines).
If the yield monitor uses the combine ground-speed sensor, check the
combine ground-speed readout while you drive. If the combine speed
readout is erratic or zero, disconnect the ground-speed cable from the
ground-speed sensor and check the readout again. If the readout is still
erratic or zero, replace the ground-speed sensor.
If the combine speed readout looks good, disconnect, inspect, and
reconnect the distribution and ground speed cable connections. Inspect
the monitor cables for signs of pinching or cutting.
Use a volt-ohm meter to check for shorts and continuity in the ground
speed cable, distribution cable, and cab cable. Refer to the Reference
section for pinouts of the monitor cables when you check for shorts and
continuity. Check for proper electrical connections, including
determining whether the ground speed and elevator speed cables have
been interchanged.
