The voltage isn't adjustable on basic models, it is a product of engine speed and capacitor end the generator bell housing. Not sure what model you have?

How do I adjust the voltage and still stay at 60Hz? Im running at 106 volts at 60Hz. Thanks for any help! Ray

Engine speed controls 60 Hz. The voltage regulator controls the volts out. Check for worn brushes if it has them. Otherwise look at replacing the voltage regulator.

My problem is voltage fluctuation, after starting generator the voltage is 380v and become 150v then goes up to 410v

I am sure the problem is the adjustment of the voltage regulator.
There are 3or4 small adjustable "pots" on the circuit board of the regulator.
You must connect an analoge volt meter to the output of the generator for this adjustment. Adigital will not work in this case. You will need to adjust the "IR" compensation pot as necessary to stabalize the voltage. This adjustment will surely change the voltage also. As you change the IR you will need to change the voltage too.
Let us know if you need more help.You may need to get the info sheet for your regulator if the pots are not cleasly marked.

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

I have a galaxy 44v that recieves keys up but know watts come out i have put new finals new voltage regulators b754 and the one in front of it changed the 300v redish " dog tic" thats what we...

  • The Galaxy 44 has 1 final and 1 voltage regulator not "finals." I doubt it is putting nothing out although it may look like it on a watt meter. Check VR16 (low power adjustment for the amp) and VR 13 (High power adjustment) for the amp in the radio. That radio has a variable power so make sure the pots were not turned out of whack. Check VR 14 as well. this is your AMC modulation pot adjustment.

  • Test the driver as well as the pre-driver. Check your microphone to make sure the wiring is good and the PTT is functioning.

  • Hope this helps and thank you for using FixYa.

I would like to ajust voltage regulator but cant find it

Pretty sure the voltage regulator is INSIDE the alternator, and you CANNOT adjust it.
If it is putting out TOO much voltage, you could tear down the alternator and repair it, but it is easier to just put a re-manufactured one on it.

Your output voltage from the alt. should be between 13.75 to 14.75. If not, or if it 'jumps' alot, then replace the alternator.
test the battery voltage with a voltmeter with the engine off, then with it on. Battery should test 12 V. + if it is fully charged.

Briggs and stratton 8000 watts generator, the output of the 120 is only 102. How do I adjust the output?

Voltage is adjusted by increasing rpm of engine. Use meter with Hz setting and try to adjust to 60 cycles and check voltage to be at about 115-120. If engine is turning 3600rpm/60 cycles and voltage is very low, then problem is most likely with brushes/ commutator rings, or voltage regulator. Some voltage regulators have an adjustment screw to bring voltage up/down (adjust to proper rpm/cycles first). Good luck

Guardian generac 10kw model 5502 does not output correct voltage

the instructions says the voltage regulator is automatic/digital. when you check the voltage is there any load on the generator? if applying load to the generator doesn't help, you can manually change the motor speed where the governor connects to the carborator, but it may change the frequency, but the regulator may fix it

Galaxy 88hl stuck on 24.178

Hello radiogeek,

it sounds like you have a bad voltage regulator since you are indicating that the voltage adjusted by L17 is random. Check all of your voltages from the power supply (regulator side), and make sure they are stable. You will find that you may have a bad voltage regulation circuit or a bad capacitor in the unit power supply.

Thank you,
