New Onan 4000 wont start
Hi. I’ve got a Winnebago 2018. Our generator has about 30 hours on it and was last used about 60 days ago. Everything worked fine. I went to crank up the generator today and it cranks, starts, and the...

I am not sure but something clicks in my mind that even though there is usually a delay in power going to the 120 vac part of your coach, the genny starts producing immediately and that the outlet on the genny receives power immediately.
Doug may step in here soon and will know for sure.
The codes are not absolute, mine were all low oil pressure, but the problem was a faulty rotor/stator assembly.
You may be able to check the voltage at the generator by plugging in anything that gives a voltage reading immediately. My DMMs don't so I use a three light outlet checker.
It may be worth a try.
I don't believe the 4KY has an outlet on the generator; at least, my (rather older) variant does not that I've ever found. To check the output you'd have to connect leads in the guts of the generator.
The delay in powering the motorhome comes from the time delay in an automatic transfer switch, which gives the generator time to come fully up to speed and for the voltage to stabilize and hopefully the choke turn itself off, etc.
