SOURCE: McCulloch fg6000mk: generator motor runs, no power.

You need to trace out the power wires the come out of the genset. They will end up on a breaker. With a volt meter measure both sides of the breaker. If one side has voltage and the other side doesn't, then your breaker is opened. Press the breaker in closed to see if it actually closes. If it don't then you will need a breaker. However, if no voltage is being produced, it is possible that the voltage regulator let go.

Hi there:
Remove the back cover and look for damaged brushes or electronic parts, I'm assuming you have some electric-mechanical skills. otherwise you better take it to a service shop

SOURCE: black max 7kw generator high voltage output

Those voltage readings MAY be normal.

The AC waveform may cause your meter to read inaccurately. You would need to use a TRUE RMS meter to accurately read the voltage.

The siple meters actually read the AVERAGE voltage and then are calibrated to mulltiply it by the "form factor" for a sine wave. OFTEN these generators don't produce a clean sine wave. A square-ish wave will read higher on the garden variety meters.

Compare the brightness of a lamp comparing to when run on your utility.

The frequency depends on engine speed ... yours is running a bit fast...check it under at least half load and if off, adjust the govenor slightly.

SOURCE: My generator is not producing

If you have NOT had an accident involving overloading the unit and it is brand new, exercise your warranty. Some of the brushless alternators can have the rotating diodes blown out if overloaded or something puts a short on the generator.

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 much output can i get from northstar 5500 ppg generator


there are two things in generator out put
one is max out put which is 5500 in your case and another is rated out put which should be about 4500 in your generator Max out put should be used only for a little time say half an hour otherwise generator is suppose to run on rated load or rated out put which is 4.5 kva or 4500watts in your set that also when you are in Ideal conditions means if you are at the sea level if you are above in altitude you can calculate that engine will loose its efficiency at the rate of 3% after every 1000 feet altitude inthat way you can calculate how much rated load you can put on the generator

High voltage rpm power generator output


Not sure what you mean "high voltage rpm power generator out", however many people have asked how to adjust the engine for proper voltage output. On generators with~out a voltage regulator, I adjust the engine RPM by using a digital voltage meter that has a Hz setting. Adjust the governor untill the meter displays 60 Hz. With the geneator producing 60 cycles, I know that the engine is turning 3600 rpm (the engine produces max hp when it is turning 3600 rpm). At this point, read the voltage output to verify that the range is between 115 ~ 120. On generators with a voltage regulator, verify/adjust that generator is producing 60 cycles then adjust voltage by turning screw at the regulator (some regulators are sealed with potting compound and can not be adjusted). If your power demands are not that great and you appliance can operate at 50 cycles, adjust governor as needed. Lowering to 50 cycles will also reduce output voltage. Good luck

How can i reduce the power output of my black max electric generator, is damaging my 60walt bulbs.


The revolutions per minute are probably too high. You will need the appropriate screwdriver and a volt meter to adjust. Possibly have another person help you. Connect the volt meter to the output with the generator running. Locate the speed adjusting screw on the carburator and adjust it one way or the other until the voltage on the voltmeter reads 125volts. Before yoy begin adjusting the carburator take note the position of the screw and then count the turns in the event you have to return to the place you started.
Good Luck

I have a powermate 3500 and when running unloaded the output voltage is around 165VAc. When it is loaded it drops to around 145. what is causing my problem. knutgar


engine rpm is adjusted to high... I set engine rpm according to a loaded condition usually while running a power tool to puts max load or close to it on the generator. I try to get it at 125VAC loaded
