Pass The wiring inspection passed. Go to Step 4.
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 4: Measure 48 Vdc power in main harness connectors P46 and
P47.
Note:
Connector diagrams are available in Step 5.
1. Verify that the engine is shut off.
2. Disconnect main harness connectors P46 and P47 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 P47. The reading should be 48 Vdc.
5. Measure the voltage between P46 pin 1 and P47 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 48 V logic power and ground wiring in main harness
connectors P46 and P47.
These are diagnostic steps to help isolate problems identified in Step 4. Use a multimeter to test the resistance
