I have a 16KW Generac generator. It is wired in with an automatic setup to turn the generator on/off as needed. It has a green light to see that everything is OK and a yellow light to indicate that something is needed. About a month ago the green light was on and the yellow light also turned on. My oil change was overdue so I changed the oil and filter. Both lights remained on. The generator is set to turn on and run for 10 minutes on Monday morning. It does turn on and run. So, now I am confused, why is the yellow light on? I appreciae any help and suggestions.
