When I adjust the engine speed to 7200 RPMs the voltage is fine and it runs my electrical quipment fine. Sounds like a bad diode/varistor. Am I barking up the right tree? How can I check/replace them? When I adjust the engine speed to 7200 RPMs the voltage is fine and it runs my electrical quipment fine. Sounds like a bad diode/varistor.

Couldn't find anything on that model number other a control box.
Assuming your in the USA output frequency would 60 hertz under load so 65 hertz would be find; although, engine is running close to 3900 rpm when it should be around 3750 rpm unloaded which would be 62.5 hertz. As the output voltage being low it is probably the AVR (automatic voltage regulator) that is the problem.
I am not familiar with this make of generator, however I am thinking that voltage regulation and rpm are tied together with this unit. The generator MUST have an output of 60 hertz. This could be 63 hz (when the load comes on it drops to around 60). If the frequency is NOT at the above specs you will burn out anything with a transformer or motor. Now this translates to around, minimum of 3600 rpm on the engine. If you have access to a frequency meter (a kill-a-watt) you can set the speed. I found it best when using the kill-a-watt to use it with a minimum of a 10 foot extension cord. Set the throttle speed so that your frequency reading is 63 hz. If this is the non electronic voltage regulated type of generator, the voltage should come up to around 120 volts and the frequency should be at 63 hz.

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?
Most of the small portable generators will depend on the engine speed to
regulate the voltage. If the motor is at the correct speed you are getting 120 volts 60 hertz, if not it will read lower like 115 volts 55 hertz or so. This can be fixed by adjusting the governor, or idle speed needle.
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
I see plenty of info on this hood on the internet - but the glaring potential issue is that the voltage and frequency in "Hertz" may be incorrect for your use.
Candy is a UK manufacturer and likely builds all their appliances to function on 240 volts at a frequency of 50 Hz (Hertz). If you're trying to get this hood to work in North, Central or the northern portion of South America (and a couple of other places, too), it won't work. The "normal" power supplied by utilities in these parts of the world is 110 - 127 volts at a frequency of 60 Hertz.
You may encounter considerable expense to replace the motor with a 120 volt type - but you should be able to get a light bulb working - but you'll probably have to swap the lamp holder or socket if it is a simple incandescent type - if something else - it'll cost some more.
Please rate this reply if it was helpful - good luck!
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.
you will needs a power transformer adaptor form 220 volt to 110 volts at 50 hz at the out put/because current there is 220 /50 hertz and us is 120 at 60 hertz..
hope that will help you

check for a circuit breaker that is tripped, as well as a switch that enables 240volt (at the cost of 120 volt current being cut in half.). The switch puts the alternator windings in parallel (120volt full power) or series (240 volt @ half 120volt current).
When I adjust the engine speed to 7200 RPMs the voltage is fine and it runs my electrical quipment fine.
Sounds like a bad diode/varistor. Am I barking up the right tree?
How can I check/replace them?
Is it running at normal speed?
