Step 4: Test the power and ground wiring in main harness connectors
P46 and P47.
These are diagnostic steps to help isolate problems identified in Step 3. Use a multimeter to test the resistance
between the following pairs of locations:
Location Harness
1 Main
2 Main
1 Main
2 Main
1 Main
2 Main
Pass The resistance tests passed, but the voltage readings in Step 3 are still bad.
Note:
Do not go to Step 5 until after the voltage readings in Step 3 are good.
Fail One or more of the power and ground wiring tests failed. Repair or replace the worn or damaged
parts. Go to Returning the Machine to Service (page 22)
Step 5: Swap cutting reel motors between cutting units.
All of the cutting reel motors are identical.
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. Swap cutting reel motor 1 with a cutting reel motor from a different cutting unit. You can obtain more
