Generator 7kW LP Model 04389-3 when started goes to over speed

I have a Guardian Plus Generac Generator. When I try to start it either manual or automatic, it starts right up then goes to over speed and shuts down. What could the problem be. It was fine and my husband put in a new battery and the problem began.

If this is one of the big "taco cart" portables you need to check that the vent on the gas cap is open when you're running the engine. In the center of the gage on the gas cap is a little knurled knob, turn it counter clockwise (lefty loosey), about a half turn or so and run the generator.
If that doesn't solve your problem add to it here, otherwise please give me a rating I'm trying to build a little credibility here and could use the help.

That sounds just about right, if the relay contacts get welded together it sometimes takes out the driver on the printed circuit board. As you found out, 12vdc from 23 to 194 makes the transfer switch move to the Generator position, relay not energized makes the ATS move to the Normal position.

You can make a nice test function by installing a 10 amp contact switch in series with either the N1 or N2 terminals. When the switch is open the generator thinks the Normal power has failed.

Regards,
Carl

SOURCE: 2nd battery explosion with 3 year interval of flawless operation.

If the unit is using a wet cell acid battery, it's possible that dirt mixed with hydrogen build up on top of the battery caused the second failure. The battery top should be kept clean and should be checked at least 4 times per year. Any stray ignition source can cause the hydrogen to explode, including lightning.

It's also possible that the battery float charger needs to be adjusted or possibly has a problem. Some float chargers are adjustable. The higher the charging rate the more off-gassing the battery will experience and increase the chance of a failure.

If the battery has exploded, the entire generator and housing should be cleaned (washed) thoroughly to remove any remaining battery electrolyte (acid).

Be careful - if you aren't comfortable working on this type of equipment, it's best to call a local dealer and find a service vendor.

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

Mount the transformer on the generator. Hard wire it into a 120 vac plug. Run wires to the module and connect to the coil on the relay. Now run the load you want to disconnect while the generator is running to the load terminals of the relay in the module.

    If you are using a Manual transfer switch, then you should manually operate the system. Why don't you use the switch it came with? Why would you use a 200a manual transfer switch on a 17kw generator? The idea is to move your critical circuits into the transfer switch panel. Then it would operate in auto.

    If the generator is out of warranty, you can try spraying a short shot of ether into the intake of the generator as it is running rough. If the engine smoothes out for a few seconds, and returns back to original state, then it is likely running lean. Check the gas regulator (this is LP or natural gas I am assuming since it is standby), the vent may be clogged on the bottom of it.

    Start runs shutsdown


    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)
