Returning the Machine to Service (page 22)
Step 4: Measure 48 Vdc power in main harness connectors P44 and
P45.
Note:
Connector diagrams are available in Step 5.
1. Verify that the engine is shut off.
2. Disconnect main harness connectors P44 and P45 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 P45. The reading should be 48 Vdc.
5. Measure the voltage between P44 pin 1 and P45 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
P44 and P45.
These are diagnostic steps to help isolate problems identified in Step 4. Use a multimeter to test the resistance
