Returning the Machine to Service (page 22)
Step 4: Measure 48 Vdc power in main harness connectors P40 and
P41.
Note:
Connector diagrams are available in Step 5.
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 Step 6.
Fail The voltage readings were not good. Go to Step 5.
Step 5: Test the power and ground wiring in main harness connectors
P40 and P41.
These are diagnostic steps to help isolate problems identified in Step 4. Use a multimeter to test the resistance
