Generator will not put out electricty

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. ... When the residual magnetism is lost, the generator will produce no power at start-up.

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.

Make sure you unplug the brush wires from the automatic voltage regulator or you will damage the regulator. Do not contact the voltage regulator or other wires as dangerous voltages may be present that can cause electric shock.

Is there any inline fuses that may have tripped. I had a similar problem many years ago and I needed to have the internal windings restrung / rebuilt. After this procedure my unit ran flawlessly and even above normal spec outputs

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.

Residual magnetism of the rotor out. Lift one brush off the slip rings and flash a 12 volt battery on the rings. Reconnect brushes and start engine no output? Repeat then seek help as I need to put my grippers on it to check

Water is used to spin commutators in armatures of generators which in turn produces electricty. For example: Niagra Falls helps generat electricity. Do a search on Niagra Fall generators.

sounds like problem with c board still a problem

If the engine is running but no output from the plugs....the VERY common problem is loss of magnetism in the generator after storage.
With the generator off.........
Look at the side of the generator part.....do you see a small + and - on any terminals?
You may have to take a cover off.
Take a 9 volt battery and momentarily put current from this small battery through these terminals.
Now.....start her up and check for power at the plugs.
This fixes 75% of "no output" after being "stored" generators.

There is no such thing as "remagnatized" thats horrible and stupid advice. Your engine once started turns an alternator, which that produces electricity. Check all wiring connections first, if everything looks okay, you may need to replace the alternator.

Specs do not mention a maximum safe rpm but the recommended shaft speed is 3600rpm. Even though it isn't a premium product I can't imagine the manufacturer would be so foolish as to design it so it breaks if that speed is exceeded by a reasonable amount for a short amount of time. The big question is what is a reasonable amount - I reckon a safety margin of 25% would be reasonable for a budget priced product and up to 40% for a premium product.

Over-revving is unlikely to do very much damage to the stator but the armature is at risk of damage and being brushless or self-energising, unless there is visible damage it is a difficult item to test without dedicated equipment.

I suggest you recheck all plugs, connections and cables and if no faults are found contact the manufacturer or dealer for advice, costs, etc...
