Kohler 5EKD

Hi - I have been trying to resolve issues with this generator the past two years. I had the generator running for about 12 minutes and it shut down and it has a "145.2 Fault Check Engine" code. Does anyone have access to service manual that would identify the issues related to this code? Thanks in advance for any help. It is a 2013 SeaRay 330 Sundancer.

This may help if you don't already have it

I was unable to locate that specific code but may want to look through it to see if it helps you? Good luck

Thank you. I probably need the service manual.

Bob email me and I will send you the Service Manual. Just sent you a PM with my email.

Thanks for sharing the service manual mdolesh - So the check engine fault seems to indicate a fuel issue. But the generator starts fine just stops after about 10 minutes.

Ok just realize the 145.2 on my
original post was the hours!

So just ran generator again and ran for about 10 mins and shut down with an “overload” code. Checked the manual (thanks mdolesh).
Overload
Power Limit Warning
An overload condition exists when the controller senses the generator is overloaded. If sensed, the controller will display an overload warning for 30 seconds and if no action is taken to reduce the load during these 30 seconds, the unit will shutdown on an overload fault. Action to take: Reduce the electrical load. Review the troubleshooting chart in Section 3.

so I reduced the load and it ran more than 10 mins. I checked back around 15 and the coolant was bubbling in the overflow reservoir. So I shut it down.

Last week when the generator
Got hot it started losing coolant from the inlet cap so I replaced that this week. Any thought on why the coolant would be bubbling like that?
