Information:

- The voltage is 2.0 DCV of the system voltage. Proceed to test step 9.
NOT OK - The voltage is NOT 2.0 DCV of the system voltage. The voltage is NOT correct. Repair: Check the wiring and recheck the fuse "F2". Repair the wiring or the components or replace the wiring or the components. Stop.Test Step 9. CHECK FOR DIAGNOSTIC CODES
Make sure that no other diagnostic codes are active.
Check the upper display for any active diagnostic codes.Expected Result:Only CID 0566 FMI 07 is active.Results:
OK - Only CID 0566 FMI 07 is active. Proceed to test step 10.
NOT OK - A fault other than CID 0566 FMI 07 is active.Repair: Correct the other fault. Proceed to the corresponding troubleshooting procedure. Stop.Test Step 10. CHECK THE CRANKING VOLTAGE
Turn the ECS to "OFF/RESET" and then to "START".
Measure the voltage from TS2-39 to TS1-2. Expected Result:During cranking, the voltage should increase to greater than 4.0 DCV and then stabilize between 1.5 and 2.0 DCV.Results:
OK - During cranking, the voltage increases to greater than 4.0 DCV and then stabilize between 1.5 and 2.0 DCV. The voltage is correct. There is an open circuit between TS2-39 and TS2-40.Repair: Check all wires for abbrasion or worn spots in the insulation. Check the wires in the control panel and the geerator housing. Repair the wiring or replace the wiring. See Testing And Adjusting, "Schematics & Wiring Diagrams". Stop.
NOT OK - During cranking, the voltage does NOT increases to greater than 4.0 DCV and then stabilize between 1.5 and 2.0 DCV. The voltage remains low. Proceed to test step 11.Test Step 11. CHECK SUPPLY VOLTAGE OF PEEC.Fuse "F4" remains removed from the relay module. Prepare to make a voltage measurement at the PEEC electronic engine control.
Turn the ECS to OFF/RESET. Turn the ECS to START.
Measure the voltage from the positive supply for PEEC (PEEC connector contact 1) to the negative supply for the PEEC (PEEC connector contact 21).Expected Result:The voltage should be 2.0 DCV of the system voltage. The system voltage was previously measured in test step 3.A.Results:
OK - The voltage is 2.0 DCV of the system voltage that was previously recorded. The supply voltage is correct. The problem is in the PEEC electronic engine control or the harness ihas failed.Repair: Refer to the specific Service Manual for the Electronic Engine Troubleshooting. Stop.
NOT OK - The voltage is NOT 2.0 DCV of the system voltage that was previously recorded. The voltage is low. Proceed to test step 12.Test Step 12. CHECK THE VOLTAGE AT TERMINAL STRIP 1 (TS1).Fuse "F4" remains removed from the relay module. Prepare to make a voltage measurement at terminal strip 1 (TS1) in the generator terminal box.
Turn the ECS to OFF/RESET. Turn the ECS to START.
Measure the voltage from terminal TS1- 6 to TS1-2.Expected Result:The voltage should be 2 DCV of the system voltage that was measured
