Onan 7000 - won't run when hot - code 47
Hi all, Generator has been finicky lately. Last summer we drove 5000 miles out to Nevada and back (to SC) and the genny didn't have a hiccup in all that heat. This summer, on our latest trip it...

First thing I do when my generator works off/on is check the wiring. I clean the connections and use some deoxit or similar - cost nothing. Another common issue sometimes associated with phantom shut downs are flaky fuel pumps and control boards.
Good tip. Can't hurt to clean up the connections, the genny certainly gets a lot of gunk around it with travel / use.
I also thought I might as well change the fuel filters, I think I'm around 450h and realized the svc manual specifies that interval to replace them.

TriumphGuy,
How long have you had this generator? What oil are you running in it?
Our Onan 7000 had an issue that if I used the multi-viscosity oil recommended by Onan, it would often shut down while travelling down the road, but only during the hottest days of the summer.

That's really interesting ... I thought the low oil was a code in and of itself, but don't remember. Will have to check :)
We have owned this coach for almost 3 years now, bought used from the original owner. He was meticulous about maintenance, and we had no issues with the genny the first two years.
Will keep this thread updated with progress. I hadn't found much on the forums about the code 47.
Thanks!
