Step 7: Inspect the wiring for cutting reel motor 3.
1. Go to Preparing for Troubleshooting and/or Testing (page 22)
2. Unplug the 48 Vdc battery disconnect to prevent unexpected cutting unit operation. Refer to
and Disconnecting the 48 Vdc Battery System (page
3. Disconnect main harness connectors P40 and P41 from the cutting reel motor cable connectors mounted
on the traction unit.
4. Inspect the 2 cutting reel motor cable connectors and the 2 main harness connectors for damage,
corrosion, debris, and proper alignment of the pins inside the connectors.
Pass The wiring inspection passed. Go to Step 8.
Fail One or more of the inspection checks failed. Repair or replace the worn or damaged parts. Go to
Returning the Machine to Service (page 22)
Step 8: Measure 48 Vdc power in main harness connectors P40 and
P41.
Note:
Connector diagrams are available in Step 9.
1. Verify that the engine is shut off.
2. Disconnect main harness connectors P40 and P41 from the cutting reel motor cable connectors.
3. Rotate the ignition key to the O
4. Measure the voltage between pins 1 and 2 of connector P41. The reading should be 48 Vdc.
5. Measure the voltage between P40 pin 1 and P41 pin 2. The reading should be 48 Vdc.
6. Rotate the ignition key to the O
Pass The voltage readings were good. Go to
the steps listed.
Fail
The voltage readings were not good. Go to Step 9.
Step 9: Test the power and ground wiring in main harness connectors
P40 and P41.
1. These are diagnostic steps to help isolate problems identified in Step 8. Use a multimeter to test the
resistance between the following pairs of locations:
If the fault follows the cutting unit, repair or replace the cutting unit. You can
obtain more information on installing and adjusting the cutting unit in the Setup
section of the 5010-H Operator's Manual. Go to
and/or Testing (page 22)
If the fault repeats at the cutting unit 3 position, go to Step 7.
If the fault no longer repeats, note the position change of the cutting unit in the
maintenance records for the machine. Should the fault repeat in the future,
troubleshooting may be resumed where you left off. Go to
