Question about Generac Guardian Ultra Source 15,000 Watt Portable Generator #04582

Open Question

The 15000 watt generator has only 60 hrs on it. Was running on Easter because of power outage an it quit putting out voltage for no apparant reason. No breakers are tripped and fuse is good. Can anyon

Also the engine runs great. It reved up after lights went out as though it is under no load.

SOURCE: I have a Generac 15000 watt portable generator. It

I have solved the flooding problem . unfortanetly you must remove the carb to fix it. once you remove the carb you need to remove the fuel bowl. In the bottem of the fuel bowl there is a electronic seloniod that controols the amount of fule going to combustion. this aria had varnish and gunk built up around the plunger of the selonoid, long story short clean this out with carb and chook cleaner and put it back together. start her up and she will run like a champ.

Suggest you go to Amazon.com and do a search for the Generac Guardian. When you find it, look in the product details and you will see Product Manual (PDF) under the Product Details.

http://ec1.images-amazon.com/media/i3d/01/A/man-migrate/MANUAL000031765.pdf

it has a troubleshooting guide located on page 19.

No Battery Charge DC output.



1. Battery posts are corroded. 1. Clean battery posts.

2. Battery cable is bad. 2. Replace cable.

3. Battery is defective. 3. Check battery condition; replace if

defective.

4. Receptacle is bad. 4. Contact Authorized Service Facility.

Hope this helps!

When i start the generac 15000 it starts fine but once a load is put on it it will die aS SOON AS THE LOAD STARTS IT JUST QUITS


Check the governor and throttle for easy movement. When the load increases, the governor should advance the throttle to keep the speed up.

The generator kicked the breaker of and was smoking and smelled like electrical


What type of load (electrical) was hooked up to this generation?? If the surge voltage and current was exceeded above the generator maximum for any length of time. There problems, it could be the regulator, insulation burnt off the windings.


I am taking a guess here. Now, 7100 Watts is it typical surge wattage. This mean that the generator will deliver 7100 Watt (voltage times current) this is know as the power factor. The actual operating load would be 6800 Watts and I would even operator the generator at its peak wattage. Something in the neighborhood of 10--15% less the peak wattage. Therefore a good positive theatrical Wattage would be 5800 to 6350 operating wattage. Then this generator would run all day.



Just remember Ohm's Law. Current plays a big factor in loading of a generator while the operation voltage is at 120 AC Volts. Example: electric motor; Now electric motor when starting will pull three time its operation current. Operating current for a 1/2 HP AC motor is 6 amperes but start this electric motor will require 18 amperes. This is one reason why they starting capacitors on smaller electric motors. Larger three phase electric motor can literal stop a generator cold...in its tracks. It put such a large demand on the generator it stops the engine powering the generator. I have seen crankshaft break because the generator could handle the heavy current load.



Remember, any time you are running a small gas powered generator. All ways figure what the load and surge current load will be before hooking up any generator. Normally this is figured in VA (volt/amps). Wish you lock. GB...stewbison

My generator works but the lights in my house pulse. Any ideas?


You can think of AC power as a sine wave. It goes from 0 to its peak, back to zero, to its negative peak, and back to zero. This is called a "cycle". Your generator puts out a certain voltage (probably 120/240) at a certain "frequency" (probably 50 or 60 HZ). 60 HZ (hertz) means that 60 "cycles" happen each second. Essentially, in one second, voltage falls to zero 120 times. So all lights flicker, even when connected to the utility (just so fast that your eyes can't pick it up).

With that said, how evident is the flickering? Are these lights incandescent, flourescent, HID? How many watts (or kilowatts) is the generator rated to output; how much power is being drawn?

Model pm0525312.18 serial 914080230 engine runs good but the voltage drops of from about 125volts to 90 volts when you put on about 1500 watts. does this model have a voltage regulator? what is a bridge...


According to the parts pdf, there is no voltage regulator. Voltage is adjusted by the rpm of the engine. If your have a meter that reads hertz (Hz), you can set the engine rpm by adjusting hertz to 60 cycles (Hz). At 60 cycles the engine is running at about 3600 rpm. Most engines develop their max horsepower at this rpm. If you are loosing power/voltage and the engine speed is not dropping below 3600, than most likely could be problem with capacitor, brushes or diode (bridge diode). The diode converts ac voltage from stator to direct current to power the magnet (rotor). Check for brush wear and test capacitor for value printed on part. It should test with 5% of stated value. Diode can also be easily tested with meter. Good holidays

Visit this site http://www.perr.com/phpBB3/ and they can tell you how to flash your generator. Might I suggest you run the generator often and put it under load even if you're not depending on its power output at the time like you would in a power outage. Like use it to power a shopvac or similar device.

Honda generator em 1800


Honda generators are very reliable and are easy to adjust. The best way to check for proper output is to use a meter that can check cycles and voltage. Set meter to htz or freq and adjust the engine governor to 60 cycles. When the engine is turning 3600 rpm it is at max power and the generator may be producing ac voltage ranging from 115 to 125 at 60 cycles. When you draw power from the generator the engine governor will try to overcome the stress and maintain 3600 rpm. The engine must be well maintained to produce full power. Service oil, filter, plug and valve adjustment. Some engines have a spark arrester installed in the muffler that may become blocked with carbon. If engine is producing full power and voltage/amps is low then check brushes, capacitors, and/ or voltage regulator. Most problems occur when too much power is requested from rated generator. Example, trying to connect an 1800 watt air compressor to generator. The compressor may draw double the stated wattage upon starting and cycling. For longest generator life, It is best to use only 75% of rated output. On an 1800 watt generator use max wattage 1350. If you actually need to use 1800 watts then the best generator would be a 2500 watt. enjoy
