Kohler 20resa 20kw Home Emergency Backup Generator - Page 7 - Answered Questions & Fixed issues

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

Oil pressure, or no AC output from the stator, check stator and rotor for resisitances and shorts.

Check the block heater

Low water temp is because the engine block heater and/or thermostat has failed, or the outlet it is plugged into is dead.

Check oil and pressure switch, then stator for AC output, rinhs and brushes.

If it won't start in manual, you have a short and/or a bad control board. Make sure battery polarity is correct, did you disconnect battery charger before removing old battery? If not charger can push DC volts over 20V and can damage control board.

The governor and / control maybe your issue. Also if you have the electronic governor model, check the speed sensor screwed in near the fly wheel, it should have approx 2VAC on it during crank.

Check oil pressure and sensor first

If it runs that long, you may have a bad oil pressure switch, loose connection, or fuel pump. You didn't indicate whether the time was under laod or not

Check control circuit fuses, if you cannot hear the solenoid energizing even. If it is clicking and the battery is good, check starter windings
