  1. Check for any blown fuse and replace. It can be traced directly from the output lines.
  2. Check field excitation. The field excitation is supplied by the battery to the excitation coil through a pair of carbon brushes. If the brushes are worn out, no excitation field is supplied and no output is generated. Replace carbon brush if found worn-out.
  3. Use an analog multitester to check the continuity of the carbon brush and the field coil.

When the generator does not supply output voltage one of the following is the problem.:
1-blown fuse, or a breake in the wiring.
2-a breake in the wiring of the coil or the armacher.
3-the AVR card is out of order.
SOLLUTIONS:
1-change fuse,or wires.
2-change coil or armacher.
3-change AVR card.

Can hydrogen run a generator to produce hydrogen perpetually?


No. We all can't be versed on every aspect of our world but some parts are important to keep us from falling into poor investments and scams. There are several laws of thermodynamics, essentially how energy works in our world and are a fundamental part of our understanding of physics.

One of those laws suggests that energy like arithmetic will not change unless something operates to change the numbers. The energy that is put into a system (2 + 2) is always going to equal the energy that goes out of a system (4) So just as 2 + 2 is not going to suddenly equal 5 or 6 the energy we put into our system is not somehow going to create more energy. The best we can hope for is to create a system that will somehow gather more energy from another source like solar panels. In this case it is like saying 2 + 2 + 1 equals something more.

In your suggestion you want to add hydrogen to a generator and then use the resulting electricity to produce hydrogen by splitting water and then use that hydrogen to run the engine. But you are leaving out some of the elements. The engine is probably no more than about 25% efficient. That means that 75% of the energy in the hydrogen fuel you use is used to create heat and is lost to friction. So far your equation then looks like 2 + 2 - 3 . The generator also loses some energy to friction. Add to this it takes more energy to split water into hydrogen and oxygen than we recover when hydrogen and oxygen combine to produce some excess energy. So in every step along the way we are losing our desired goal to losses in energy like heat and friction.

But even if the system were somehow perfect it could not be any more perfect than to lose no energy. You will not be creating new new energy with such a system. Even if we could get it to run forever the system is not going to give us new energy we could use for something else as every bit would be used to run the system. This is why we say that efficiency can never be greater than 1 or 100%. And we can not have "over unity" or "perpetual motion" machines.

If we want "free energy" what we could do is make solar panels. And then use those solar panels to gather additional energy from a source outside the system and then produce hydrogen from solar energy. What we can't do is use a solar panel to produce electricity for a light that shines on the solar panel as once again this would be a closed system with no energy flowing into the system.

When it comes to energy systems look for the source of the energy. If it is supposed to be coming from inside the system perpetually then it is likely a scam. If there is an outside source it may be useful depending upon the economics and how much energy we get relative to our energy investment.

I have an energy storm lifan 3600 watt remote start generator and since changing fuel in tank it starts and runs at full rpm only and will not idle down. Any advise on fix would be appreciated.


read you user manual but most small gen sets on starting come up to full rpms and stay there regardless of the load situation
it is the rpms that maintain the output voltage and cycles that has to be correct for when a load is suddenly applied

We are a NGO in Guinea where there is no electricity. We are working with a generator to power our fridge. My question is if we can connect an energie station to the generator to charge it and then later...


well i guess it ok to use or connect energy station..but you need a higher battery to use.because we are talking fridge here..i think number of batteries you need for long life of the energy station..i suggest why trying solar energy to save much fuel..i hope it helps..

We have a Valsi 5500 watt generator that isn't putting enough voltage out to run everything in out small travel trailer. It runs the lights but doesnt push out enough voltage to carry the A/C, microwave,...


How long have you had this generator?
Has the generator worked on all of these loads before?
Model 5500 is a 5500 Watt generator which could easily be 5500 watts (Peak) and not continuous.

Your AC is an inductive load.
Your lights are resistive loads

An inductive load can cause issues when starting due to an increased current demand at start up that some generators cringe under. Do the lights flicker or are they stable? I'd say your diodes on your stator are working if you have light stability but you haven't provided nearly enough information for a detailed solution.

I'm sure you have enough voltage but you aren't getting enough current to run specific loads. How many watts is your AC? How many watts for your microwave? Both of these units demand a great deal of energy to run and when you place too much demand on your generator, it will choke it out and eventually, will cause damage to the generator. You may consider getting a beefier generator with a greater amount of wattage output.


Seeing these specs online and noting what you are trying to run, you have an undersized generator and need to get one that can produce a greater amount of running wattage (as well as peak wattage).

Have an fg5700ak runs ok but no power output what


Typical diodes are 10 amp for these. The stator and rotor both have VERY low resistance readings. The reading typically will be below that which will register MEANINGFULLY on the digital meters.

My generator had 10 amp diodes with surge protectors across them. One of the protectors shorted and generator output was zero. Mine is a 6KW diesel silent unit.

Replaced the diodes with 70 amp ones with surge protectors that have 20 times the energy absorbtion as the originals. Unfortunately this required some lathe work to make holders for the diodes and the surge protectors to ride on the rotor.

Used the light bulb trick to remagnitize it once diodes were replaced.

6.5 RV Onan generaotr wont kick in when loaded. checked automatic transfer switch and excited it manually, worked one time but never again,


1. Does the generator stay running when you start it the first time?

2. What color is the housing on this generator? Try to get the model number and serial number.

If the genset is shutting down on the first try, then your probably not creating voltage. However, if this is an older unit then the genset may stay running although no voltage is created. Place a volt meter on the genset to check for output voltage.

Electric generator not producing electricity


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
