FG 5700 AK generator starts and runs perfectly but has no output electricity. A meter across the 120 volt outlet reads 1.1 volts. I assume the rotor needs some residual magnetism to start the generator, could this machine have lost the residual strength to where it cannot start? All windings and components seem to be ok and it was working a few weeks ago when last used. What can I test to know what is wrong with this generator? Thanks, Ted

First, I'm not a Coleman Tech.
* First check the generator for a wire(s) output description. This will confirm what each wire is producing and where it should be connected to.
* The specs will also give you an idea of what to expect from a particular generator. (Don't expect 220Volts from a 120 Volt small generator.. Hence the 120 VAC generator will only have 3 wires instead of 4 wires for a 220-240 Volt generator. DC/AC generator will have 5-6 wires.)
* In general, on/off switch on the electrical part of the generator (the actual electric source) is on once the engine is up and running. Electricity is being produced at this time. The on/off switch is usually the main electrical breaker that is rated for the full output of the generator. This is very similar to your house breakers except for a modification of the hook up terminals used to wire in this safety component. Like most breakers there is an input(s) then output(s). Usually the input lines will be black, white, with an additional green wire that is also connected to the frame of the generator. These three wires will hook up to one side of the breaker or the "Line In" side or "L1,L2" The other side of the breaker should have been hooked up directly to the 1 or 2 duplex (120VAC) outlet panel.
* on larger generators that produce 120/240 VAC 1PH (two 120 volt AC outputs with alternative 220-240 volt AC) There will be an additional wire that may be the same or different color IE; 2 Blacks, Reds, or Blues. This is hooked up in similar fashion to the breaker except there will be an additional section to the breaker or even two single breakers stuck together with a bar across both switches. (again similar to a 220 VAC breaker used in a house panel.) The extra wire will go to the 2nd section of the breaker. The other side or "output" of the breaker will be wired directly to a set of Duplex outlets (a pair or 4 outlets) AND a 4 pronged 120/240 1PH outlet "Twist Lock" style. (though you may find specialized outlets for single purpose generators.)
* Larger generators may also have a DC (12 or 24 VDC) wire which is of a different color from the AC wires. Expect it to be Black, Red, or White. (Black or white is probably the negative with the Red as positive.) If you do have DC wires then it's more than likely the AC wires are of different colors to avoid getting the DC mixed up with the AC side.
* Final; check your warranty. Have your vendor or MFR perform a service and annual maintenance check which is a good idea as they can change out your air and fuel filters. Check and clean the spark plug. Make sure everything is working properly. The peace of mind is worth it.

Measure the Generator after 10 minutes the first measure but not only to one power outlet with doing a measure with a multimeter its not done so because the generator is fully unloaded then you will see 105 vac
Measure on one outlet and use a paint stipper a 2000 watt type and measure at the same time on the second power outlet with a multimeter on AC you should get more volts out to measure instead of 105 volts then you hear that its generate power and blow more smoke you will be seen a 115 or 120 volts if you increase this generator its possible you get if you are increase the idle power to 120 volt can create an over loading of 200 volt or more over the outlets that can give damage if it the stator electric field generate power outside its level it can blow up your expensive tools and in a short time you think there is not enough power on my tools anymore then your armatures are become bad and the tools are hot in a short time warmt dissipation has blow up armature and nothing smels hot but the tools are blowing up. and you see nothing inside because the tools will not are getting black burned and hot but the to high magnetic pulse burns the weak points inside the armature in a fraction of time.
Beware of that the adjusting is normally doing with a tacho meter and a suggestion of about 3000rpm and not more of the stator what its max depend on model . but adjust by the load power of a working paint stripper it can have enough if you adjust 120 volt by load.

Make certain the voltage switch is set to 120 volts, not 230 volts.

check the voltage regulator

I have the same problem and here is my troubleshooting steps I took.

1) Verified that the unit had no output with induction meter on cables coming out of top of generator head (three black and three white). You can use a volt meter too.
2) Checked that brushes were free and long enough.
3) Checked capacitor (condenser) was 130uF
4) Checked diodes

The reason for the 120/240 volt outlet is to be able to run things like large electric heaters or even your clothes dryer as they all require 240 volts. If you use it as 240 volts you will not have maximum current output on your other outlets so you wouldn't be able to plug anything really big in. And yes you can only use is as a 120V output if you would like but you will need a special attachment or extension cord. I'm going to leave you with two reference pages I looked up that you should have a look at.

I found out that the gasoline motor was turning too fast so I had to turn down the speed of the motor with the adjustment screw.

Please check the owners manual.and see if the 6250W is surge power or steady state...it is not unusual..for this to occur...possibly the generator needs to be adjusted ( sped up slightly )..do not let the 120 volts output exceed 126 volts...

Hi, You don't say whether this is under load or not but if not is within the acceptable range, which is +/- 10% . Generally speaking, voltage on a generator is not the issue but the load which it will carry, hence their wattage ratings. Measure your household voltage and you will see that it varies from day to day but usually stays within the limits and your electrical panel is rated in amperage. Hope this answers your question!

probably your AVR card is burnt...
an AVR card is located right outside the stator...looks just like an AK-47 clip (i don't know how else to describe it)...i put a pic below this.
replace it and check again
