Step 6: Measure 48 V power in main harness connectors P17 and P18.
Note:
Connector diagrams are available in Step 7.
1. Verify that the engine is shut off.
2. Disconnect main harness connectors P17 and P18 from the cutting reel motor cable connectors.
3. Rotate the key switch to the O
4. Measure the voltage between pins 1 and 2 of connector P18. The reading should be 48 V.
5. Measure the voltage between P17 pin 1 and P18 pin 2. The reading should be 48 V.
6. Rotate the key switch 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.

If the fault follows the cutting reel motor to the new cutting unit, replace the
cutting reel motor. Go to Step 5.
If the fault repeats at the cutting unit 1 position, go to Step 6.
If the fault no longer repeats, note the position change of the cutting reel motor
in the maintenance records for the machine. Should the fault repeat in the
future, troubleshooting may be resumed where you left off. Go to
