Had a power interruption last night and generator did not start. After the storm passed I shut the main breaker in the electrical panel to simulate a power failure and the generator did not start. Opened the cover this morning and saw the overcrank red light on. That was the the only light on. Checked batter for power and it was o.k. Tried to start manually but would not crank. The only sound it made was a loud click.

    Checked condition of battery with two different hydrometers. Both showed each cell excellant and fully charged.



    I hear the solinoid opening and I can smell the natural gas, but still the generator will not start. This is a new battery, less than two years old.

    I will attempt to troubleshoot the power and grounding issues tomorrow morning, but can you tell me what would cause the overcrank waring light to come on?

  • 051792 Jul 13, 2009

    I have checked and there is power at the starter. All connections seem to be good, secure and not corroded. There is a good ground bond from the generator to the ground rod.

How is the battery condition? The click you hear is the starter solenoid pulling in. Check all the connections at the battery, engine ground and starter including the solenoid. You have to 'load test' the battery. Just reading the voltage on the terminals isn't good enough, a near dead battery will read 12 volts with 'no load'

    Check power at starter motor terminal. Check all the connections and make sure ground wire is tight.If you have power at the starter terminal, make sure the engine ground is solid back to the battery.

    It must be a bad starter motor then. I want you to try one more thing though, when all else fails, hit it with a hammer! I'm serious, they get hung up; give it a couple good wraps with a hammer.

    The ground rod bond is for the generator electrical system. I'm talking about the battery ground. Make sure the engine to battery neg is good.

    I'd have to say you have a bad starter motor. If there's power at the starter, and the ground going back is good, it's a bad starter motor.

I have a 16kW Generac Guardian Generator with a 200 amp house service RTS panel (installed 2007). Last night the power went out and the generator started but the unit did not switch to use generator

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 !.

Surging

It definately sounds like a fuel problem, lack of fuel..I assume it is running on LP or natural gas. The hose running from the demand regulator goes to the carburetor/mixer. When it gets to the carburetor, there is an adjustable main jet. It is different on different models, but is usually easy to find. There is probably a screw slot in the end of the screw head and a spring under the head. Start it up after locating the screw and open the jet just enough to even out the running. It was factory set, but barometric pressure and altitude and different fuels in different areas will decessitate different settings.
Please let me know if this fixes your problem, Robert

Will not turn on after a blackout

Turn off your breakers and then back on. There are fuses located in the a/c control panel. Check them. If you aren't getting any power still, a board may have been blown during the storm.
