Your generator is equipped with a battery trickle
charger that is active when your unit is set up for
automatic operation. The trickle charger is
designed to help extend the life of your battery by
maintaining the battery when the unit is
not running.
you will need to review which circuit bord controls this and have that board replaced or serviced some of these gen heads have this built in and it will be the rectifier in the gen it self it will be a black 1x1x3/8 inch with a mounting hole in the center and 4 lug post for the wires replace this and your issue should be solved but consult your dealer for witch unit you have as to a control board external or the built in rectifier hope this helps.

My cousin has one of these models and the same thing happened to his. It was the natural gas regulator valve that went out. He could hear the clicking noise which is the spark ignitor trying to ignite the gas pilot light. After replacing the gas regulator the unit work fine as ever

Unplug the oil sensor.
The oil sensor is located behind the oil filter. I unplugged the oil sensor and it fired right up. Plugged it back in and it runs fine.
It might be because it is cold.
I don't know why but I turned it off and it starts right up now.

Was oil filter changed as well ? This may result in low oil pressure shutdown until filter is filled with oil. Is there a sump oil level sensor that has stuck when oil was drained and now causing a no oil shutdown ? The battery indicator may not be real if the battery is ok.

The problem with the repair service is another matter. Emergency generator and it's switch gear are there for emergency purposes. It has to be exercised periodically. The switch gear should have a toggle switch to simulate a power outage. the switch cuts power to the sensor sensing power from the utility company. This tells the switch gear that power was lost, start the engine and switch over to generator power. Run for a period where engine reached running temperature and switch back to stand by to shut down. Do this periodically, and be grateful the event was not a disaster. Think of your back up electrical system as the spare tire of your car and similar equipment and enjoy your investment. Good people brings you happiness, bad people brings you experience !.
