Kohler generator runs fine at dock shuts down under way

[desperado]

generator starts fine at dock and after about 10 min or so of cruising it shuts down. In cabin there is an AF fault code.

CO monitor not alarming but something shutting my genny down while under way

Thoughts ?

Missing vane on impeller or bad impeller causing over heat condition?

Impeller perfectly fine. AF fault. I’ll track it down eventually.

Hi. I know this is an old post but did you track down the problem. My generator shuts down immediately with AF code in the cabin panel. No issue with CO detector (tested) and jumped the two white wires (common and NO) which bypass the relay and CO detector and generator still reports AF and won't stay on. I only have one CO detector. Thank you.

Sorry. Meant to write I jumpered NC (normally closed) and Common.
