Just curious if there other fans of the green anchor.
Yes, count me as a fan of the Onan. I have them in my two coaches and love them. Add to that the many Onans that I have repaired at GMC work rallies at my family's compound. Unless they have a rod hanging out the side (which I have never seen) then I can make any of them run. The design is perfect for our coaches from the standpoint of being 1800 RPM, the cooling system which is intended for operation in the closed compartment and also the simplicity of the generator section and its excitation circuit. What could be easier than a bridge rectifier, a voltage clamp and a PT/CT transformer?
There are, of course, improvements that can be made to the ignition system which will help a lot and the original control boards are sketchy after 40 years of exposure to the elements. I have developed replacement choke mechanisms, electronic ignitions (not the Bovee kit), electronic voltage regulation and also replacement field assemblies which are the common failure items.
I marvel at the negative attitude taken by some GMC owners - especially those on the fakebook group - toward the Onan. The troubleshooting process is straightforward and logical however many get discouraged when they post about a problem and are rewarded with a cacophony of scattershot replies ranging from "get rid of it" to any number of other "replace this, replace that" approaches of blindly trying to throw things at the wall and see what sticks.
