There could be several reasons why the output voltage of your generator is not within the normal range. Here are a few things you can check:
If you are unable to identify and fix the problem, it is recommended to have a professional technician diagnose and repair the generator.
SOURCE: voltage output is only 50 volts instead of 120 volts
More than likely your voltage regulator is out. The generator produces electricity, so you know the rotor and stator are OK. The 50 volts comes from the magnets permanent properties. The reason you are not getting 120 is because rotor or electron magnet is not getting any power supplied to it, which it needs to produce the amount of electrons you need to have 120vac. Make sure your engine is running at 60 hz first, and you should ohm out the windings and circuits that connect to your regulator.
SOURCE: Runs great but will not produce electricity
To flash the excitor circuit on a coleman ( the generator is built by generac) you need a 12 volt battery. You quickly apply 12 volts via your 120vac recepticals. NO MORE THAN ONE OR TWO SECONDS! Then check you ac voltage. Most of the time the brushes are burnt up when voltage is low. Check the brushes first. You can access them by taking the end cap off of the generator via two to four screws. The brush holder is easy to spot, two wires leading to the front of the amature. Hope this solves your problem.
SOURCE: I have a Coleman Powermate 5000 / No power output
Two suggestions. One: check for voltage from the secondary coil wires (if it has one). Two: unless stated do not do this, I have always flashed the excitor circuit through the 120vac receptical. Give these a shoot and I hope it works for you.

Hi,
If the generator hasn't been used for awhile the rotor may have lost it's magnetism. All you need is to re-excite it. There are several websites that explain how to do this. It's a good place to start.

SOURCE: My generator runs but will only put out 3.8 volts
I'm not sure what
AVR = (automatic voltage regulator?)
You could try to excite the generator pg.7

Check the brushes pg. 7
Check the capacitor

Other than that you could open the box where the outlet is sometimes the wire breaks off or comes loose even if its new. Good Luck
The EU3000 series generators are inverter generators. The generator features an alternator, which produced high-voltage, multi-phase AC power. This power is converted to DC power and then converted back to AC. This process is controlled by a microprocessor and is necessary to provide stable, consistent power capable of running equipment sensitive to power surges. This type of generator provides higher fuel efficiency and lower operational noise ratings in a lighter model than home and work generators produced by Honda.
The Honda EU3000i Handi is a 3,000-watt inverter generator that features wheels, folding handle and a recessed convenience light. The engine is a Honda GX160, which features a 163-cc displacement. The AC output is 120 volts, with an average rating of 2,600 watts and a maximum production of 3,000 watts. There are three receptacles to include a 20A, 125-volt duplex and a 30A, 125-volt locking plug. The DC output is 12 volts and 100 watts. The EU3000i can hold 1.56 gallons of unleaded fuel, which will provide consumers with 3.6 hours of run time at 25 percent load for 7.7 hours.
