Portable Generator For Sale

What causes a gas generator to stop putting out voltage?

The engine runs fine and I cannot find any blown fuses. but it is not putting out any voltage The generator is only about a year old. Although it is an off brand name. I havent found any switches to turn the plugs on and off.

1. i dont know but i can tell you how they work. first off the power you get to your house and all of the power that is supplied in an electrical companys grid is supplied by a generator. the portable generator you have works the same way. they work like this- now when you place a conductor (metal, copper, silver, gold, ect.) in a magnetic field electricity is produced in that conductor. then they found out that when they have two magnets opposite of each other and when they are spinning in a circle they produce a much stronger magnetic field causing more electricity in the conductor when the conductor is placed in the center of this circle or magnetic field. so that is how the generator produces the electricity. now these portable generators work off of gas while the power companys generators work off of steam which is produced by burning coal- why is this needed- gas or coal is another source of power and this power needs to be used to spin the magnets in a circles to produce the strong magnetic field which produces electricity in the conductor. so you could have a problem with the motor that spins the magnetics not allowing the magnets to spin causing to electrical output. the conductor could of came loose or one of the magnets could of came loose. i dont know why your generator is not working but they all work in this way i hope this helps
2. This is a tough one to answer without knowing more about your generator. For example, older generators may have a problem with worn brushes, while newer generators are designed to operate without brushes. Either or new generators may have problems with that insulation of the windings. Make sure you check for an on-off switch to turn on power to the outlets. Hope this helps, but we really need a little more information - even to make a best guess.
3. The likelihood is For the DC side is the diode pack (bridge rectifier) has been destroyed. The AC side is a different matter. You must check the brushes in the motor exciter. These might be worn or the slip rings are dirty. XX
4. Here are the two most likely causes. With more information I may be able to assist further. The voltage regulator board could be damaged. It will need repair or replacement. If it is a brushless generator without a regulator board the field may have weakened and needs to be flashed.
