Case IH AFX8010 Repair Manual page 1128

B. If the voltage reading is less than 10 volts, there is excessive resistance between the batteries and the
cab fuse panel, due to loose or corroded connections, or the batteries have discharged excessively, and
are not capable of supplying the minimum voltage requirement for CCM2. Inspect the wiring from the
batteries to the engine compartment, and from there to the cab. Recharge or replace the batteries.
7.
Key switch in "On" position. Move the propulsion handle (MFH) out of neutral. Enter the Universal Display
Plus "DIAG" screen. Select the "GROUND DRIVE" sort menu, and select "HYDRO VOLT" to check the
voltage range.
The proper voltage supply is 10.0 - 18.0 volts.
A.
If the voltage reading is between 10 and 18 volts, continue with Step 8.
B. If the voltage reading is less than 10 volts, there is excessive resistance between the fuse panel and
CCM2. Inspect the following wires for loose or corroded connections, or damage:
- wire 010 red, fuse F42 to Cab Power relay K26, terminal 3
- wire 007 orange, Cab Power relay K26, terminal 5 to buss strip
- wire 108 orange, fuse F48 through connector X001 pin 3 to RH harness splice
- RH console power wires to propulsion handle S-03, front switch panel A-13, rear switch panel A-18
and RHM connector X026 pins 4 & 5
- wires 300 orange, 110 orange & 1180 orange, RH harness splice across separator switch S-30 to
neutral switch S-02 connector X059 pin 3
- wire 113 yellow, neutral switch S22 through connector X001 pin 17 to CCM2, pin J1-17.
Locate any damage and repair.
8. Start the combine engine. Enter the Universal Display Plus "DIAG" screen. Select the "VOLTAGE" sort menu,
and select "CCM2 BAT" to check the voltage range.
With the engine RPM at low idle, engage road and work lights. Check voltage range.
The acceptable voltage range for the module is 10 - 18 volts.
A. If the voltage reading is between 10 - 18 volts, continue with Step 9.
B. If the voltage reading is less than 10 volts, the alternator and/or regulator may have failed, and the
charging system is not producing sufficient voltage. Refer to Alternator - Problem solving (A.30.A.82 -
G.40.A.30) for additional alternator testing information.
9. Operate the machine while observing the Universal Display Plus "DIAG" screen.
A.
If no low out of range readings are detected, erase the fault code and continue operation.
