No power output on customer's John Deere 6200 portable generator

Tool Type
Generator
Difficulty
Medium
Time
1-2 hours
Tools Used
Pliers, Socket set, Nutdriver
Parts Used
1. Check for power output at receptacles (No go)
2. R&R end cover & generator end plate. Clean slip rings on rotor. Check brushes for proper contact.
3. Check for min. AC output from rotor and stator while running. (OK)
4. Replace AVR. Check for generator output. (No go)
5. Disconnect + and - leads from brush block. Start generator and flash rotor with 12vdc.
6. Re-connect brush leads and re-start. Check for output. (OK!)
NOTE: On this type of AVR *always* make sure all leads go to the proper terminals. The AC voltage sense and AC input to the AVR are different size terminals, but it is still possible to get the individual leads mixed up and the generator won't put out at governed speed. Be sure to follow the instruction sheet exactly on the positions of the voltage sense & AC input wires to the AVR! (The wires have numbers printed on the insulation)
