If this is one of the big "taco cart" portables you need to check that the vent on the gas cap is open when you're running the engine. In the center of the gage on the gas cap is a little knurled knob, turn it counter clockwise (lefty loosey), about a half turn or so and run the generator.
If that doesn't solve your problem add to it here, otherwise please give me a rating I'm trying to build a little credibility here and could use the help.

SOURCE: Guardian generac 10kw model 5502 does not output correct voltage

the instructions says the voltage regulator is automatic/digital. when you check the voltage is there any load on the generator? if applying load to the generator doesn't help, you can manually change the motor speed where the governor connects to the carborator, but it may change the frequency, but the regulator may fix it

SOURCE: I have a 17kw generac generator that will run

I have the 18KW model and was told that most alarms relate to a low battery. Make sure the battery charger in the Transfer Switch is properly feeding the battery or hook up a mobil battery charger to the battery and see if the alarm goes away. Good Luck.

low voltage can be from incorrect running rpms

Generac troubleshooting my generac 14kw generator engine runs why doesn*t it produce electricity


Assuming the generator circuit breaker is on, depending on the model it could be the voltage regulator or the slip ring brushes or both. If it's a portable it could be a capacitor problem.

Under voltage alarm /shutdown on generac 10 kw gen.


The brushes on Generac automatic units are most likely not lined up with the slip rings and will wear down and burn out very fast. There is no way of checking this during assenbly because they are hidden from view and the generator has to be dismantled to be able to replace them. It's an extremely poor design and Genrac should face a class action lawsuit for producing this piece of junk.
