Further update.
After the Genny was out of the Motor home It was taken to Bailey electric in Corfu. Further Testing disclosed that the ROTOR windings are bad not the STATOR as I was originally told by a local shop.
For everyone's info and after much searching the rotor in my Genny if purchased from Cummins would be about $1000.00. Rewinding is in the $400 - $450 range plus shipping
Only 2 places that I found in the U.S will bother rewinding a rotor my size
#1 Eurton Electric Co., Inc. 9920 Painter Ave Whittier CA 90605 POC John@eurtonelectric.com
#2Quality Armature 5259 W. Grand Ave. Chicago, IL 773.622.3951

Hope this helps someone in the future
