Onan generator problems.--Update Problem solved.
I have a an Onan 4000 series microquiet generator Model 4kyfa26100a in my coach.
while running generator today it developed a problem .From cold start generator will run fine under a load for about thirty minutes and then will start surging,not a major surge but more of slight up and down throttle.at this point the generator will start flooding and will finally quit.
it will immediately restart but when load it applied it will do same thing and then quit.
generator can sit for a couple of hours and restart fine and run about 30-45 minutes and problem start again.Also I've noticed that it seems to be getting extremely hot while this is happening.
Update:
After checking what I could I decided generator had to come out of coach.(thank god for motorcycle jacks)I lowered generator enough to remove cover.It seems a mouse family had taken up residence in my generator.
They had blocked air flow in fan area.I cleaned everything up and reinstalled generator and fired it up .The generator ran about five minutes and quit.After more troubleshooting I found that my fuel line from tank had rusted causing a couple of pin holes in the line.
I replaced the line and restared generator,after four hours run time I believe all is well.
