Check the battery voltage while cranking the engine if it drops below 9 VDC then you have a bad battery.

SOURCE: It is a Guardian-Generac Generator Model 0052410.

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

SOURCE: I have a guardian 15000 generator. Have not used

Hello, I tried to answer this problem you had a few days ago. You were worried the hurricane was come and your generator wouldn't start. I tried to post the answer but Quest has the slowest servers were work properly. To many customers and not updated servers. Anyway I hope this help you out.

First, replace the fuel filter. When taking out the fuel filter let the gas in the run into a can. This will help to remove any sediment in the fuel tank. Buy a couple of fuel filters. One problem is it where you live. Condensation builds up in the fuel tank and this create rust. When the hurricane is over. Remove the fuel tank, and have it cleaned out. Now, see if they can line the fuel tank inside with a plastic coating. This will stop the rust. Also, insert absorbents packs in the tank when the generator is idle. This will will help the moisture build up.

Second, change the oil and remove the oil pressure shut off sensor and clean it or replace it.
If it has a temperature sensor take it out and clean it. If it has a oil filter change it also.

Third, remove the spark and clean it or replace it. Make sure you have the right plug gap on the spark plug..

Fifth, use some carburetor cleaner and spray around the throttle place and choke plate and make sure that the governor arm to the carburetor is free to operate and everything in the carburetor is working freely.

Fourth, remove the air filter and clean it or replace it.

Sixth, remove all the fuel in the tank and filter the fuel with a couple pair of your wife's pantie hose.
Be really careful, gasoline is extremely explosive.

Seventh, remove the fitting from the tank and use compressed air to clean out the tank. You might think I'm going to far here. Once you think the tank is clean install all the brass fitting and hose and new filters and pour the filter gas back into the tank. as long as it is new gas, if it's fuel old depose of the old fuel.

Next, Never used starting fluid on gas engines. If you get to much starter fluid in the combustion camber it can explode and blow the head off or nock the top of piston off destroying the engine. You and your family be safe. GB you all....stewbison

Hello i just started my 8 kw hole house generater ran greatput my electric water heater on 26 amp draw andsmoke came out exhaust vent shut it down ran again great turned only heater on again took amp

8 kW has a 35 amp breaker on the unit. A typical hot water is 4500 watts at 240 volts = 18.75 amps on each leg. If you are measuring 26 on one side and 19 on the other it should be ok. If it is shutting down you may have a fuel problem or you may need to adjust voltage if it's too low. Which model of 8 kW is it?

Check the inlet fuel pressure, on exervise there is no load, when power is out it is loaded and demands more fuel. Also check for bugs blocking gas regulators vents etc

Generac Guardian 12 KW Model 04456-2 shuts down on overspeed in cold weather

See my 5/22/12 comments on my "overspeed fault" problem resolution [Generac 43903 standby Generator overspeed indicator on starting] . If it only runs for a few seconds and then quits, you may have a similar condition to the one my unit had. A good technician should be able to diagnose the problem and determine if you have a similar failure to the one I had, or one of the other causes suggested by RSG000.

Generator starts up and then cuts out after 7-10 seconds. The cut out appears to be from a "shut down" switch as opposed to carburetor oriented (it's natural gas).

I don't recall, does your generator have oil monitoring, did you say you checked the oil. If it's a protection shutdown there may actually be an oil change timer as well.
