Please call me if you'd like. Genrac 13 KW Code says Stopped Alarm Under Voltage. Its not the battery. Generac said natural gas supply similar to maybe an air pocket?? It turns on for a minute then dies out. Is it a carburetor?
Expert:  Hank F. replied 1 year ago.

It is very doubtful that the carb is the issue. It is morel likely something else.

What is the serial number of the genset?

OK

What you need to do is a procedure called the "Fixed excitation/rotor amp draw".

Do all of the steps, and let me know the results.
