How do I get my generator to make power again???

I have two techniques for flashing the field on my web page.

If the engine is working fine, but there is no output voltage try this trick. It may work on standard alternator type generators, but not on those which use an inverter. It worked for me in the past, but try at your own risk. First check to ensure that all circuit breakers and fuses are ok. Shut off the engine and remove any cords from the generator. Plug in a cord with bare wires on the other end to one of the 120VAC outlets. Connect one end of the cord to a car battery. Very quickly touch the other wire to the other battery terminal. Do not leave it there longer than to create a few sparks or you may destroy the windings. If the residual magnetism in the alternator had weakened, this may be enough to get it started again.

As an alternative to flashing a rotor winding with a battery applied to the brushes, an electric drill may be used. Follow these steps to flash the generator:

Plug the electric drill into the generator receptacle. (Cordless drills do not work)

If the drill is reversible, move the direction switch to the forward position.

Start the generator

While depressing the trigger on the drill, spin the drill chuck in reverse direction. This will excite the field and the generator will now produce electricity. If spinning the chuck one direction does not work, try spinning the chuck in the other direction as you may have the reverse switch positioned backwards.

Use caution not to get your hand or other materials caught in the chuck. As soon as the field is excited, the generator will produce power and the drill will turn on.

The reason this works is because the electric motor in the drill will act as a small generator when spun backwards. The magnets in the drill's motor induce a voltage into the motor windings, which is fed back through the trigger, cord and into the generators receptacle. From there it goes into the power winding of the stator. The voltage going through the power winding creates a magnetic field, which is intensified due to the iron core of the stator laminations. The rotor intersects this magnetic field as it is spun past the power winding, thus inducing a voltage in the rotor winding. Once current flow is present in the rotor winding the rotor has been flashed.

If flashing the field does not make the generator work, you may have additional problems, besides a lack of magnetism in the rotor. Further testing will be needed.

It is possible that a generator loses its residual magnetism, that is the small amount of magnetism left in the iron after the power is removed. This is needed to start off the generation.

Ideally this is resolved by applying a dc voltage to the rotor but since that would mean stripping the generator down, it is often done at the output terminals. Of course this is potentially dangerous because the generator will start to generate immediately which could cause the batteries you use to explode.

Simple solution is to make sure the wires to your battery contain a fuse. when you do it. The generator needs to be running.

I have also seen something for sale on Ebay to do this, which is basically a battery and a fuse.

Homelite Generator 5000

the generators rotating coil is wrapped around a steel core that has a little bit of magnetism only if that little bit of magnetism was lost would it be necessary to polarize it

and that never happens .you will find the problem by doing the following

check the 110 outlet for continuity with an ohm meter (should be less then 20 ohms ) if its open its got a bad or tripped circuit breaker. or the stator winding is open.

if you have continuity then you need to remove the cover

and check the diodes that supply the dc to the Field coil (the coil that turns )if they are good check that the two brush's are making good contact with the slip rings finally check the Field coil for continuity by touching the two slip rings that the brushes ride on with your ohm meter. do all these tests with the generator not running.

This procedure is known as flashing the field. Remove the the terminals of your stator field winding and impress the therminals of a 12- volt battery for 3 minutes or more. Then restore the connection. Do the same in your rotor winding. Remove your slip ring brushes and impress the 12-volt DC on your rotor. Restore the original connection after 3 minutes

I have a homelite 3000 watt generator. For some reason it won't generate electricity. I am told that I need to "liven" the "field" or something. Kind of like arcing older autotmobile alternators to make them start to generate power. Does anyone know how to do this??? Someone...

if your generator has been sitting unused for a long period of time it may only need to have the fields charged but I would have it done by a professional it only takes them a minute. Besides if you do it wrong it may damage the electronics.

A deeper cause to your problem my be a part called the stator which is expensive. Mine cost me about 350.00 recently.

connect a drilling machine on the output side of yo genset, it should be one of those drilling machines that have reverse modes, remember to this while machine is running, spin your drilling machine to the opposite direction, your drilling machine will act as a generator when span reverse this will restore your residual magnetism on your rotor, if this fails you may need to spin it to the other direction your genset will produce power so be carefull to remove yo hands

I would try to contact the manufacturer (e-mail address?) for instructions first, especially if still within warranty. If they do not have good customer support, why trust their generator in an emergency, right?

connect a wire to the battery positive then touch the wire to the " A " terminal of the generator for a second or two. this excites the field of the generator and restores charging.
