Make sure that the throttle linkage is all there and not damaged/misadjusted, then get a manometer and check your inlet gas pressure. Gas pressure should be 8 inches of water column and stay there running or not.

SOURCE: how do I reset the low tire warning message/light?

With the 2005 Monterey, you need to activate the system check by pushing one of the command buttons on the lower dash right of steering wheel. Have it do a system check where it will cycle through the various things that it monitors (i.e. door, lighting brake lights, ect.). It will come to the tire pressure and ask if you want to reset it, simply push and hold the reset button and the light will/should go off.

Generac generator manual


Usually generators that have stood for a very long time loose the magnetism in the ignitor coil magnet. With care, if you can find the low voltage wire into the generator 'motor' you can apply a 9v battery briefly to it and spark it into life. Use the generator if you get it generating, for a good period and don't leave it unused for a long while.

The battery could be bad. Try to measure the battery voltage when you try to start. If the battery is bad then the voltage will drop quite low when the battery is loaded with trying to start the set. If you can borrow a similar battery you could just try with it.

Generac 43903 standby Generator overspeed indicator on starting


I have a generator that did the same thing. It would start and then stop within a few seconds. The more expensive generators have an oil level safety switch to prevent the engine from burning up. There is usually a wire connecting to the switch on the outside of the engine near the oil fill hole. Remove this wire and try to start the generator. If it runs without a problem then it is the switch. You need to remove the switch and take it apart carefully and clean it. There is a small float inside the assembly. When the oil runs low the float allows the switch to short to ground which kills the spark to the spark plug. Hope that helps.

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)

20KW Guardian Generac does not produce 12 volts to run engine


The problem is that the printed circuit board inside the generator draws a little current from the battery even when the generator is not running. Over the course of a few days this can make the battery weak enough to be unable to get recharged by the built in running charger which results in not enough power to run the electronic governor on the generator. Usually the spark plugs will work even with a fairly low battery.

Most of the Generac generators come with a built in trickle charger that runs off of the transfer switch load terminals. If your built in charger isn't doing the job it's either broken or you have the wrong sort of battery installed in the generator.

Regards,
Carl
