What is the "no load" generator voltage supposed to be...my EB6500X Honda generator is putting out 262 volts and 131 volts when measured at the generator receptacles which seems too high...is there any way to adjust it down if these values are in fact too high...?? Thanks... Doug

Okay I see your answer. I will research this tomorrow but my first instinct is that two volts is probably right. The pulses are low voltage and trigger the spark electronically using low voltage power which is then amplified. .

Voltage regulator, carbon buildup in the cylinders, the carburetor may need overhauling, engine governor may have a stretched spring, Spark plug may need replacing, Timing may be off, air filter may need changing, and lastly, your load may exceed the ability of the generator.Checking this list will uncover the loss of power

Measure the Generator after 10 minutes the first measure but not only to one power outlet with doing a measure with a multimeter its not done so because the generator is fully unloaded then you will see 105 vac
Measure on one outlet and use a paint stipper a 2000 watt type and measure at the same time on the second power outlet with a multimeter on AC you should get more volts out to measure instead of 105 volts then you hear that its generate power and blow more smoke you will be seen a 115 or 120 volts if you increase this generator its possible you get if you are increase the idle power to 120 volt can create an over loading of 200 volt or more over the outlets that can give damage if it the stator electric field generate power outside its level it can blow up your expensive tools and in a short time you think there is not enough power on my tools anymore then your armatures are become bad and the tools are hot in a short time warmt dissipation has blow up armature and nothing smels hot but the tools are blowing up. and you see nothing inside because the tools will not are getting black burned and hot but the to high magnetic pulse burns the weak points inside the armature in a fraction of time.
Beware of that the adjusting is normally doing with a tacho meter and a suggestion of about 3000rpm and not more of the stator what its max depend on model . but adjust by the load power of a working paint stripper it can have enough if you adjust 120 volt by load.

Is it putting out that voltage with or without load? Speed will influence these units, depending on the model the capacitor regualtor in the back end of the alternator is subject to this error. If you have an AVR then it mayeb adjustable depends on the unti you have. Try measuring engine rpm to be sure it is withing specs first. That is not so high a voltage as it can be 10% of nominal. I am sure it drops down under 1/2 load, then all is ok

You cannot, speed is propertional to voltage on these, as they have capacitor voltage regulation. Do not use this for powering home appliances, it is common to see this design and not a problem. If you add load and it will decrease but so will the frequency

Yes, the extra Voltage can overload the Relay. You have several problems here. The Batteries are suppose to be connected in such a way to give you 12 Volts. If you are measuring Voltage to the Relay without the engine running, the main battery cables must be wrong. But one of your batteries must be shorted because two X 12 Volts is 24 Volts, not 16. Unless your dash Voltmeter is pegging out at 16 Volts; you are really getting 24. Use a Multimeter set to Volts and retest to see what the actual Voltage is.

If you are measuring Voltage after the engine is running, the Regulator is bad and allowing too much Voltage in the system which can burn out about anything designed for 12 Volts. It would not be much of a factor for the Glowplug Relay though, because it should shut off before you crank your truck. So in theory you would not be generating 16 Volts while the Relay was working.

You can get a free load test on the Batteries and the Starter at Autozone, Oreillys, and Advance autoparts. Ask for a charging system test. Some Walmart stores will test, but I do not know if it is free.

I hope my solution is very helpful in providing you some items to check to cure your problem.

The voltage can go down provided the engine RPM drops off. So check if the oil change and scheduled maintenance was done on time.
If the RPM is set up according to the load , the voltage will rise up , but if the voltage is low the Load connected can also be high.
So if in dry load the generation is low you might need a full check up,overhauling/cleaning out of the alternator, engine to get his back to shape.

Most low voltage conditions on generators are simply due to a low engine rpm. Most modern generators are 2- pole windings. So your engine rpm should theoretically run @ 3600 rpm. which will produce 120/240 volts @ 60 HZ. In actuality You want to set your rpm's @ Approx. 3720rpm no load. About 62.5 Hz. Without getting to technical this will give you your desired 120/240 volts loaded. Hope this helps.

Hi, You don't say whether this is under load or not but if not is within the acceptable range, which is +/- 10% . Generally speaking, voltage on a generator is not the issue but the load which it will carry, hence their wattage ratings. Measure your household voltage and you will see that it varies from day to day but usually stays within the limits and your electrical panel is rated in amperage. Hope this answers your question!

This problem is either that the engine RPM is too low (most likely), or that there is something amiss in the voltage regulation. Get yourself a DMM that measures Hz, plug it into the output and see if you get 61.5 Hz, if not look for the adjustment on the governor spring. On some Powermates this is a screw that pressed on the governor arm, on others it's a little tab the governor spring attaches to that you bend. Do this at no load. FWIW 61.5 Hz is also 3750 RPM of the engine.
