Generac Power Systems Electrical Supplies - Recent Questions, Troubleshooting & Support

You engine has a low oil level sensor. If the oil level is low or..... the sensor is bad it will ground the ignition from the coil with the engine switch on. For troubleshooing only disconnect ONE wire from the sensor AFTER you make sure the engine oil level is properly serviced. Then check for spark.

If this does not correct the problem just respond and I will help you.

You need to press down on the top lid as you unlock. This... from a girl who knows!

This 2099 has disabled my Generac after being fine for 2 yrs???

I had a similar problem and it was because I had OVERFILLED the oil! I drained enough to make sure it was within the crosshatched markings on the dipstick and it started right up.

When you get the under speed alarm is the generator under load? Try manually starting the generator with no load and let it run for a while, if no alarm, then put it under your home load and measure current draw (maybe have an electrician check it) if the amp draw and in rush caused by compressors, pumps motors etc are within the generator rating, check your fuel pressure, on average 8-11 WC Nat gas. Pressure may test well under no load but drop starving the engine of fuel unde rload. Underspeed is just that engine cannot make RPM/Frequency

under warranty , you best have to wait the time as anything you do to fix it will void the warranty which will suit the service agent just fineif you void the warranty he will get 2 hours travelling time plus the cost to repair time so don't touch it

RPM Sense loss means that the generator controller hasn't received a valid signal from the ignition coils for 3 seconds of attempting to start. Probably a dead or low battery or bad ignition coil. Replace the battery and try again. Call dealer if problem persist.

Good troubleshooting on your part. Was my thoughts that the onboard battery had failed.

Rated output is at full load. Units will produce power up to that limit and use gas accordingly. Very lite load = less output and less gas consumption, etc.

With the engine off, check the exciter brushes and slip rings which supply magnetic power for the alternator winding in the stator. Also, check the motor-to-alternator mechanical coupling. Check the breakers for tripping. To service beyond this point requires a schematic of the alternator, a voltmeter, plus knowledge of what the schematic is telling you. Good luck!

If you can get it running, run some "Sea Foam" cleaner through it. Sounds like the valves (reed) are gummed up... I don't think there is a compression release on this machine, but you can get the manural at: Generac Power Systems The best backup generator for your home business...

It sounds like the coil has went bad, replace the coil and you should be good to go

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.
