That is a full home back-up unit. You need dealer support. Contact them direct. There is nothing online about re-flashing.

Turns out it was the Manual-off-Auto switch that was bad. My DVM showed a voltage drop across the switch. The controller wasn't getting enough power.

One good thing about it was it forced me to really study the schematics to understand how everything worked. I'm now in the process of designing my own esp32 based controller, with wifi connectivity, to replace the stock control board.

The current models of automatic standby generators will have LED indicator lights on the side compartment of the generator. A green LED light will indicate that the unit is in AUTO mode and is ready to run, or is running properly during a utility outage. The yellow LED light will indicate that maintenance is needed. The red LED will indicate either that the unit is switched to OFF or that there is an alarm detected. If a yellow or red LED are present, you will need to check the generator's control panel, as it will describe the type of maintenance needed or the alarm present. This information can be found in the owner's manual as well. You can find a copy of the owner's manual online by searching the model or serial number of the unit here

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 !.

I assume you want to adjust the light output of your camera's built in flash. You cannot make any adjustments to the flash output on the L830. In fact, you cannot even adjust the built in flash on my $3,000 D800. All you can do is turn it on or off or set various modes that allow its built in flash to control other stand alone flash units such as the SB 910. You can manually control the flash output on stand alone units by instructing them to use fractional power outputs such as 1/2 or 1/4 power from either the camera menus on a Nikon SLR or the flash itself. The bottom line is that in order to control the flash, you need an external flash unit that costs more than your camera cost you.

When you plug in your system with the power cable and turn the toggle switch (in the back) do you see the red stand by light?

The red and yellow light comes from 1 bulb and the green and blu light comes from another..

If you have the YLOD and your yellow/red light is out, you will only see the green light.

I am really interested in your problem.

Do this to check your status: If you can do this function below but not any other, chances are, you do have the YLOD. It can be fixed.

Power off the unit using the toggle switch on the back. Hold down the 'eject' button and turn the toggle switch back from off to on. This will run a fan test and should eject your disc. Remember, this will only work on the 20, 40g models. Not the backwards compatible units with the 4 usb port holes and the memory card slots.

You have the infamous YLOD, aka. Yellow Light of Death. This is the number 1 cause of pS3's dying. It is an overheating issue linked to your CPU and GPU (the processor chips) You will need to find a local PS3 repair shop who can repair this. Do not try to attempt repairs seen on the internet yourself as some would suggest.You could make things much worse and render the unit totally unresponsive. The repair process takes about 3 hours.

IT CAN BE FIXED

IS THERE A DISC STUCK INSIDE?

If you have a unit that is not backwards compatible, any non 60g or 80g then you can retrieve your disc.

Typically caused by the fuel line (LP or Natural Gas) having a lot of air in it. Was your generator just installed, or was there any work done to the gas line of the building / generator? Consult local gas contractor / propane dealer / gas company for assistance in purging the fuel line.

A low battery can also cause this as well as the generator is not able to come up to starting speed quick enough. Try placing a stand alone battery charger on the generator and charge the battery. Also check the air filter as well.

OverCrank condition occurs when generator tries to start itself, or be manually started, and the starter spends too much time turning.

This can also indicate failure of the control board. This will need the expertise of generac technician. Call 1-888-GENERAC (1-888-436-3722)
