New Holland CX720 Repair Manual page 3708

A. If there is continuity, the open circuit is in the main frame (MF) harness between connector X009 pin H
and connector X008 pin 14 wire 443 blue or 425 blue. Locate the open and repair.
B. If there is no continuity to ground, the open circuit is in the front frame (FF) harness between connector
X008 pin 14 and connector X017 pin J3-18 wire 425 blue or 766 blue. Locate the open and repair.
7. The voltage reading on the InfoView monitor is high. Disconnect the grain bin ¾ full sensor S28 connector X107.
A. If the voltage drops to 0 - 4.9 volts, continue with step 8.
B. If the voltage remains high on Infoview monitor, continue with Step 9.
8. The voltage reading on the InfoView monitor is high. Disconnect the grain bin ¾ full sensor S28 connector X107.
Use a multimeter to check for voltage on connector X107 pins A and B.
A. If there is high voltage on connector X107 pin A, the regulated voltage supply is incorrect. The error
"E0165-03 CCM2 5V Ref Voltage 3 Shorted to High Source" should be listed in the "Active Errors" screen
in the InfoView monitor. Correct that error, and then check to determine if this error has been resolved.
B. If there is high voltage on connector X107 pin B, there is a short to high voltage in the grain tank (GT)
harness between connector X109 pin B and connector X107 pin B wire 445 yellow. Locate the short and
repair.
9. The voltage reading on the InfoView monitor is high. Disconnect the grain bin ¾ full sensor S28 connector X107.
Use a multimeter to check for voltage on connector X107 pin C.
A. If no voltage is found, continue with step 11.
B. If high (>4.9 volts) voltage is found, continue with step 10.
10. Disconnect the grain tank harness from the main frame harness at connector X009. Use a multimeter to check
for voltage on connector X009 pin E.
A. If no voltage is found, the short is in the grain tank (GT) harness between connector X107 pin C and
connector X009 pin E wire 400 yellow. Locate the short and repair.
B. If high (>4.9 volts) voltage is found, the short is in the main frame (MF) harness between connector X009
pin E and connector X016 pin J2-22 wire 400 yellow. Locate the short and repair.
11. Operate the machine while monitoring InfoView monitor. If no high out of range readings are indicated, erase
the fault code and continue operation.
