Check the following:
AVR
doids windings
stator windings
rotor windings
exciting windings
AND
Exiting windings could have losts its 12volt exiting load. In that case it must be exited by 12 volt external battery
Another common problem is burned off wire or loose connection

Generator is a device that converts mechanical energy into electrical energy for use in an external circuit. At present, generators are widely used in industry and agriculture, national defense, science and technology as well as our daily life.


How does a generator work?
Generator works by moving electrical conductors through a magnetic field. If your generator doesn't have magnets, it won't produce electricity. The magnetic field is created by taking some of the generator output voltage and converting it to DC and feeding it to a coil to make an electro magnet.

SOURCE: Generator will not generate electricity.

I assume it is a hand start genset. The most common problem if it has been sat for a while is rust on the ignition timing flywheel. If you take the pullcord housing off (recoil) then you will see a big flywheel with what can only be described as a big forked prong with a couple of wires on it. This flywheel should be stainless steel and rusts when sat around for a while without use. Its job is to complete the circuit to the spark plug every time the flywheel passes the forked prong at a given spot on the flywheel, the faster the wheel turns the faster the spark hence the engine runs quicker. Clean the rust off with a releasing agent (wd 40) hey presto!!!!!!!!!!!

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.

Craftsman 5600 watt generator AVR Location? It does not appear to be inside the cover of alternator.


The most common cause of portable generators failing to produce electricity is from the loss of residual magnetism.

Generators work by moving electrical conductors through a magnetic field. Your generator does not have magnets. The magnetic field is created by taking some of the generator output voltage and converting it to DC and feeding it to a coil to make an electromagnet.

When there is a small amount of magnetism left over from the last time the generator was running, it is called residual magnetism. The little bit of magnetism is enough to produce a small amount of electricity. This small amount of electricity is needed to create an even stronger electric magnet. As the engine turns this magnet moving its electric field, through the stator windings, your generator produces even more power.

When the residual magnetism is lost, the generator will produce no power at start-up. This residual magnetism can be lost naturally from not being used or from the load on your generator being connected when the generator is shut off. It can also happen from running a generator with no load for too long.

Generators need to work and it helps maintain that residual magnetism. When they are running, a load should be connected to it. It helps create an even stronger magnetic field. Before you shut it off, turn off the switch or breaker to disconnect the load. If you shut off a generator with the load connected, it can essentially drain or demagnetize the electromagnet. Try and avoid running out of fuel.

How to fix it:

There are a few methods of restoring a generator residual magnetism

12 Volt Generator Battery Method

Locate the voltage regulator for your generator.
Unplug the two wires that connect to the generator brushes. Normally one is red and the other is black or white.
Connect the black or white to the generator ground battery terminal.
Plug in a light, turn on the generator breaker or switch and start the motor.
Connect the battery +12 volts (red cable) to the red wire on the terminals you removed for three seconds.
Remove your wires and replace the plug. The generator should now be producing power again.

Why don't my generator fg7000ma generate power or only half power


Why a generator won't produce electricity?
After the unit is running, the generator rotational speed reaches the rated speed, the AC exciter stator excitation circuit switch is closed, the voltage regulator is raised to the maximum direction, at this time, the generator has no output voltage or the voltage is very low. That's why a generator fails to produce electricity.

I have a PowerBack generator. It runs but does not produce electricity. How can I test it?


by plugging in a AC lamp if it lights up it is producing electricity. Suggest looking for circuit breaker on generator as possible cause of problem.

My generator is not producing power runs fine does not make power


Could be several problems on the gen set itself. Check to see if there is a surge protection breaker or fuse, depending on age. Make sure all connecting wires are secure and switches are not set to 240v instead of 120v if you are trying to use outlets.

Generator stopped producing electricity


if the generator has been sitting for a while you might have to excite the magnets to start producing power. plug in a reversible drill and with the generator running turn the drill in the reverse direction by hand while holding the trigger in the forward position.
