Kohler 27HP Replacement Engine CV740-3001 - Page 6 - Answered Questions & Fixed issues

Disconnect the control wires and see if it still does it

Are you running the gen and plugging in the RV at the same time? I assume it is wired right and you have a transfer switch? Are you saying the voltage is fine when the RV isn't plugged in?

Over frequency is overspeed and is most likely a dirty magentic pickup sensor on the flywheel

It sound slike water impeller is not giving enough flow to the heat exchanger

Can you please list the model?

Contact advanced-power-technologies.com they can maybe help

Check oil, and sensor, rotor rings, and brushes, then stator rotor for shorts

Your problem is mag pick up, or possibly the solar panels are reverse powering the generator, if the home consumes less than solar output

The only way is with an hour meter, if you have a dealer look at it with a computer they can retireve that data from the control, if the hour meter has been disconnected etc

Contact www.advanced-power-technologies.com they can help you with that manual

What is your question about the brushes?

You do not have enough inlet pressure or volume, it's not the generator. you should have at least 9"WC cranking or under load

UU is generator under voltage. Check to see if it does it without laod also. if it does you will need a pro to check and ohm the rotor and stator for shorts

Check oil pressure switch, and oil level and type

What is the original question please?

The fuel mixture and or pressures are wrong

Check the oil pressure switch, and oil level first. Then check rotor brushes and rotor slip rings may need polishing. If the problem is still there check stator and rotor windings

I can maybe help with that, as this is an old post, if you still need it let me know

Need more information, won't start, won't crank ??? Better to let a pro take a look

Which model???? generally there is a control circuit fuse yes on most models
