Carol, I knew a fellow a few years ago who worked in a power plant. He said he couldn't prove to anyone that he worked for a living because he couldn't show anybody what he made. I think we have a similar situation with these generators. They tell us what they are suppose to do but you can't really see what they are doing. It makes no sense to me that my two 2000's in parallel work my AC perfectly and yours don't. It makes no sense why some 3000's work alone and others don't. I guess I'll stick with my level of electrical knowledge, if I push that thingy on the wall and the light comes on, something is working. If not, I'll yell for help.
