I have had a problem with my generator when you start it it would not switch to gen power after shutting the gen down and re starting it would switch to gen power.It was like clock work every other time it would work. And I had power to my line switch every time the gen would start. So the gen was working, just not switching at the line switch.
So I called Parallax Power Supply and spoke to Chuck I told him what was it was doing, He said check the Timer disable switch as they can get dirty and move it back and forth many times to clean the contacts he also said if that does fix the problem it needs to be replaced. So I pulled the cover off of the line switch and did what he said and now every time I start the gen It works
