Wonder if you would feel that way if you had to take your car to dealer and pay their prices to have work done on your car if you have the ability to do your own repairs? I can see this for warranty work because the manufacture would want to know if a qualified person did the repairs, but what about those with generators out of warranty which is only one year for Generac Guardian series, seems to me that they should have the option to do the work themselves or have a person who knows generators do the work which I have been doing for years, otherwise you open the door to price abuse when you remove any competition, our Constitution protects us from monopolizing and give us a choice to have things repairs by anyone we chose including ourself, a car manufacture who tried the same thing would be hit with allot of law suits if they ever tried to do this, there are many people who like doing their own work not only because of the money they save but the feeling of self sufficient of being able to do for ones self can be gratifying.
Now by restricting any help or parts supply they are monopolizing that only their people can do the work, I know some dealers will sell to us but many won't sell parts other then just oil filters and spark plugs without them coming out and doing the trouble shooting and the part replacement, I had one dealer claim that it was because of liability which is false since the only one liable is to the one who does the work not the part seller, other wise we would not have electrical equipment being sold by suppliers to anyone or even car parts, it's all about greed, and I want it all, the funny thing is most of these people would be the first to yell if the same thing was done to them, could you imagine the uproar if car manufactures quit allowing replacement parts from being sold to the general public?
Sorry for the rant, but things like this can get to me because I believe in the American Dream and slowly more and more is being taken away from us.
