I have just gotten in an old Kohler 950 Generator in for repair. Model 950MM25. Serial number 1007913. I need a service manual for this unit. Engine runs great, but I have no AC output. Kohler has obsoleted this units 15 years ago and my tech contact has not been able to find anything for me yet. Another possibility is does anyone remember how to flash these units. Any help would be greatly appreciated. Thanks Rivets.
