If this is an XL4000 I first check on the condition of the brushes and slip rings, then look at the voltage regulator.

Generator had been running for 3 hours with a/c and refrigerator and lights (on concession trailer)when we experienced a loss


the unit has gone into over load
The total power requirement has exceed the output of the generator
for example if the generator is a 2.500 kw or kva then it will generate well at 1.8 kva or kw but it will not run forever at 2.5 kva -kw
When a ac is running the power requirement will be constant on the generator and with the fridge as well then the load will be at the maximum out put of the unit.
when the fridge starts again the extra load will exceed the max out put of the generator and it will slow down ( lights dimming ) and eventually go into overload mode
have an accredited electrician calculate your maximum load requirement for an external power supply and then get a unit that is at least 15.. kva kw better that required
generally fridges use 1000watts , ac conditions will draw over 3000watts and any thing else adds up . I am guessing that your generator is only 2500 unit

How to start a gas generator (should the choke be in or out, to the right or the left before starting


Most Generac generators have a lever for the choke that pulls out. So if the generator is being started for the first use or cold you should choke when starting . Let it run for 30-45 sec. then push it in . Once the engine has been run or warm you dont need to choke every time when starting .

I have an older model Niagara 4kw by generac with low hours. I started it recently for the first time in 3 years. It ran fine but produced no current. I checked the brushes and cleaned the slip rings but...


I have not seen yor generator in practice, but saw some pictures of it.

As it is an older model, but it is not rare for modern generators too, when they stay a lot of time (3 years is a good lot of time), they lose thier magnetism.

In order to build the magnetic field up again you can connect for a short time (1 - 3 seconds) by a working motor, a 12 V battery to the field terminals, + and - respected. A series diode 10 - 25A to battery can stop the built up field voltage to overcharge the battery.

Installed a generac 20kw about a year ago, ran fine untill 2 days ago. During a utility outage, generator ran for about 30 minutes and then stopped producing power while still running. All mains were still...


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!

Generac Guardian 17.5KW Generator dies


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.
