Generator loses residual magmatism

Here is some reasons for reference:
1.After the diesel generator is stopped, the residual magnetism is often lost, because the material used for the magnetic pole of the exciter is close to the soft steel, and the residual magnetism is small. After the shutdown, when there is no current in the excitation winding, the magnetic field will disappear.
2.The magnetic pole of the diesel generator loses itsmagnetic properties.
3.Damage of excitation circuit components or circuit breakage, short circuit or grounding phenomena.
4.The exciter brush is not in good contact with the commutator and pressure of brush holder is insufficient.
5.Excitation winding wiring error, opposite polarity.

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.

My advice throw the dirty ice away then monitor. It could be residue from old filter or even new. This happens sometimes and usually clears it self.

Colemans were known for losing what is known as "residual magnetism", especially when sitting for long periods of time without use. This residual magnetism is necessary for exciting the field to produce electricity. Here is what you can try: Plug a 110v drill into one of the 110 outlets. While the engine/generator is running, with an open hand (not fingers wrapped around it) spin the chuck while holding the drill trigger in the run position. Many times this small amount of current that will be produced by spinning the drill motor will restore the residual magnetism and excite the field. Keep in mind that if this works, the drill motor will begin to spin immediately since it is plugged into the outlet. Hope this helps.

Without knowing the exact model generator you have, it may not even have an automatic voltage regulator (AVR).

Hello, Welcome to the world of Russian night vision system. That is right, Night Owl Optics Cyclops NOCC3 is manufactured in Russian. The biggest problem with these monocular and binoculars and even scope is that they use cheap 1st generation Russian image tubes and everything else. It would be cost prohibitive to have it fixed, that is, if Night Owl Optics will fix it for you. Hint: Auction it on Ebay as night vision parts. Sorry, GB...stewbison

They may be using a laser or some other device to "Interfere" with it, OR they maybe using some sort of "Jamming device" I go for the laser.

it sounds like you have a fuel line problem inside the tank,maybe a pinhole, once fuel level gets below pinhole the line loses pressure. once it loses pressure you have to keep turning switch on & off too get pressure built back up.

first check push button breakers on generator. let me know, troy
