Step 6: Measure 48 Vdc power in main harness connectors P48 and
P49.
Note:
Connector diagrams are available in Step 7.
1. Verify that the engine is shut off.
2. Disconnect main harness connectors P48 and P49 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 P49. The reading should be 48 Vdc.
5. Measure the voltage between P48 pin 1 and P49 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 7.
Step 7: Test the power and ground wiring in main harness connectors
P48 and P49.
