Troubleshooting
PROBLEM
POSSIBLE CAUSE
SOLUTION
Moisture reading errors (high or
low)
1. Wire disconnected or bad
connection between sensors and
ICM in cab of tractor
1. Reconnect wire.
2. Low power supply to ICM
2. Check voltage at ICM box. (Min of
12 volts required.)
3. Dry hay lower than 7% moisture
or wet hay over 40%.
3. The Bale Chute system read 6-
40% moisture.
4. Short in wire between Microwaves
and ICM.
4. Replace wire.
6. Check hay with hand tester to
verify.
6. Contact Harvest Tec if conditions
persist.
Moisture readings erratic.
1. Test bales with hand tester to
verify that 77E has more variation
than hand tester.
2. Check all wiring connections for
corrosion or poor contact.
2. Apply dielectric grease to all
connections.
3. Check power supply at tractor.
Voltage should be constant between
12 and 14 volts.
3. Install voltage surge protection on
tractors alternator.
Bale rate and application rate
displays zero.
1. Model 77E moisture only kit does
not provide a baling rate or actual
rate of preservative
MWM moisture reads low all
the time
1. Bale Rate sensor out of
adjustment
2. MWM
– Chute is not properly
selected in setup menu
1. Verify Bale Rate sensor is not
damaged and is sensing the
metering wheel moving each
time
2. Reference Moisture System
setup section
ICM light will not illuminate
1. ICM receiver not connected
2. Harness disconnected
Low power
1. Check connections and voltage.
Minimum 12.5V needed.
2. Verify all pins in ICM are not
damaged
Moisture displays as “error“ in
Harvest Tec object pool within
VT or tablet*
Moisture displays as “89” on
baler work screen
1. Damaged metering wheel
proximity sensor
2. Faulty harness connection to
microwave moisture sensors
3. No incoming crop
1. Verify proximity sensor
functioning on metering wheel
2. Verify moisture sensors properly
connected
3. Feed crop into baler
*if ICM does not see a reading from the microwave sensor
within 5 min while in RUN, system will display “error”
/ ”89%” until new reading is sent
