I am working on replacing stator and regulator/rectifier on an approximately 20 year old Grasshopper 618. Engine identification information is gone, and best I can tell it is a Kohler Command CH18. It is a fairly involved job to replace these parts. Stator was charging at 19.8 volts AC when tested. Should be about 28 volts AC. When you are in there with engine shroud off, be sure to check snd clean cooling fins. See very few Grasshopper zero turns and I am glad. Not a fan at all.Model 618 serial number 5415475 2004 grasshopper
Thanks that does help i did find the regulator will test itI am working on replacing stator and regulator/rectifier on an approximately 20 year old Grasshopper 618.

I replaced the stator and regulator/rectifier yesterday, and still getting no charging, and 50 volts AC from stator. Never had this problem after removing and replacing stator. Any suggestions other than the flywheel may need to be replaced?Thanks that does help i did find the regulator will test it
Star Tech-Flywheel won't need replacing as you are generating the require output voltage.
You do have the regulator grounded don't you? It would not be the first time I have seen other techs to forget to ground the regulator case.
Also is the battery voltage at the B+ when not running? These regulators do require standing battery voltage to present in order to operate.
