September 2003 6-11
Problem Cause Solution
Moisture Readings of
5% or Erratic. Bad connection or
damaged moisture
cable. Check temperature reading. If it is –20 degrees
there is a bad connection or cable damage.
Check moisture sensor cable where it connects at
the distribution cable and cab cable. Look for
pins that have corrosion or any part of the cable
that has nicks or may have been pinched.
Ground strap on
moisture sensor is not
getting a good
connection. Ensure the ground strap touches bare metal where
it contacts the sheet metal.
Moisture Sensor is
excessively worn. Check Moisture Sensor for worn plastic at the
base of the fin. Damage to the fin. Worn
temperature sensor element (a good temperature
sensor element is copper in color). If any of the
above conditions are present replace the Moisture
Sensor.
Moisture is too high or
too low. Temperature
calibration has not
been performed. See Calibrating Temperature in the Calibration
Section.
NOTE: If the temperature calibration was
incorrect and you correct it, check the moisture
calibration again.
Moisture readings are
high. Moisture sensor or
auger tube has an
accumulated sticky
buildup. Clean any buildup from the sensor blade and
auger.
If buildup is so severe that the moisture sensor
will not stay clean adjust the moisture setting
manually. See “Moisture Setting” in the
Operation Section.
Moisture reading
decreases
drastically/suddenly. Determine if reading
decreases occur when
using a business-
band, two-way radio. Move the radio antenna and cable as far from the
moisture sensor and sensor cable as possible. If
the antenna wire must cross the moisture sensor
cable ensure it crosses at a 90-degree angle.
Erratic moisture sensor
signal with moisture
sensor installed in auger
tube. The flighting of the
combine grain tank
fill auger was not
completely cut down
to the shaft where the
moisture sensor was
installed. Remove flighting completely to auger shaft
where the moisture sensor installs
