I must say I am a little taken back surprised that the feature I have been discussing is not commonly known.
Here is Owner Manual for EC-30 (from Onan)
https://onan.xmsi.net/900-0541B%20On...0(12-2007).pdf
You can see all of the details wiring drawings for installs etc. But to get right to the point go to page 5 of the manual
(Preventing Automatic Starting when connected to Shore Power AC)
Pages 7 and 8 explain the detail of how it works. Look at bottom right of page 7 and all of page 8.
You will see where I am going from the functions
SP SENSE AFTER to
the SP SENSE BEFORE
I will gain the ability of
#2 for Genset to shut off when AC power is present from Shore and
#3 auto start upon loss of AC power, Onan refers to it as automatic backup system.
I hope this help clarifies for all. Sorry for any confusion on my part with terms or definitions. I just want them to get it fixed. It was my first real oh oh moment with a Winnebago Dealer and I thought I would share. The coach was returned back to them within 18 hours of my pickup yesterday. I will give them some time to advise as to what happened. Last night; I had vision or hope that some little red button may have been missing for easy fix; as to not have to cancel my trip, but those plans are toast now.
