Question about Electrical Supplies
What kind of your generator? Please say details, thanks.

Yes, there must be a protection device on the unit somewhere. It should be indicated in the owners manual. It may be on the box the outlets are in, or built into the cover of the generation unit.

SUBURA COLEMAN GENERATOR RUNS FINE..IT RAN OUT OF GAS AND MY UNCLE FILLED IT UP AND RESTARTED IT..HOWEVER HE LEFT EVERYTHING PLUGGED..LATER ON, WE NOTICED IT STOPPED SENDING ELECTICAL CURRENT TO THE PLUGS..DOES IT HAVE A FUSE OR DID SOMETHING POSSIBLE BURN OUT...HAVE NOT HAD A CHANCE TO TAKE THE COVER OFF TO SEE

SOURCE: I have a 5550 generator
Hello, it sounds like either you have a voltage regulator failure, the rotating field coil is shorted or opened, or the exciter windings have failed. No easy answer because there are a number of issues here as you can see. Depending on how old the unit is you might have warranty. I would suggest you take it to a generac service center to have it checked out. I have 30 years experience with generac units. If it is a voltage regulator issue, (this can be expensive) you can get a jobber regulator. This link is for a good generic substitute.
I have used this regulator on 4000 watt to 50 kw units successfully. If it is a winding, then to rewind the stator part of the generator is expensive and a new generator is cheaper.

Hi and welcome to FixYa, I am Kelly.
Without a model number... I am guessing about what type / brand and MODEL of generator you have. I have to assume it is a Coleman Power mate.
Try flashing the field. Do this.. take and electric drill and plug into the outlets of the generator. Turn on the output power GENERATOR ON. Squeeze the drill trigger and rotate the chuck as fast as you can. This will induce voltage into the stator and they usually will start producing power. When it does produce power it will try to yank the drill chuck head out of your hand so keep that in mind.
If the above does not work...
Remove the small cover from the center of the endbell. It covers the end of the rotor shaft and has 2 brushes under the cover.
INSPECT the brushes visually (do not remove them yet)
Use a meter to read resistance by probing the electrical contacts of the brushes. You MUST read LOW resistance. This is the rotor winding.
No resistance or high resistance
Remove the brushes inspect for damage. Try to probe the slip rings of the rotor. (You might have to make a 14/2 Romex electiral wire extension to get some solid copper wires to touch the rotor slip rings) Again you must read LOW reistance.
If you have low resistance and the brushes are good.....
Reinstall the brushes. (TEST for AC) Start generator
STILL NO OUTPUT?!!!!
Use a meter on DC to read AVR voltage output to the brushes by probing the brush terminals. You should read 3 - 7 VDC. No voltage.... hmmmm Possibly an AVR problem but...
Rig up a 9 Volt battery that you TAPE the wires to the battery terminals and the case of the battery
Just loosely connect the 2 wires to the brushes. Wrap the battery with a rag it might explode if you don't remove it fast enough. Your going to yank this off as soon as it produces power QUICKLY.
Plug in a light or a small fan so you can see that power is being produced. Let it run a few minutes before shutting it down.
To do anything else I need to know your generator model number to do winding and voltage regulator checks.
Thanks for choosing FixYa,

If there is no power to the receptacles:
1. Turn the circuit breaker switches off and disconnect all electrical loads from the generator.
2. Turn the circuit breakers on and test the GFCI's by following the procedures in this manual
on page 1 -
TO TEST A GFCI:
Start the generator. Turn the auto idle switch off. Push in the TEST button (A) on the receptacle.
The RESET button (B) will pop out. Power is now off at the receptacle.
If the RESET button does not pop out, the GFCI is not working. Do not run
generator until the problem can be corrected. To restore power to receptacle,
push the RESET button in. If the RESET button pops out during operation,
stop the generator and check the generator and equipment for defects.
3. Place the voltage selector to the 120 Volt only positions (unless you are using a tool that
requires 240 Volts).
4. Turn the idle control switch off.
5. Turn the circuit breaker(s) off and reconnect the electrical loads. Be sure that the plugs are
securely connected to the receptacles.
6. Turn the circuit breaker(s) on.
7. If there is still no power at the receptacles, take the generator to an authorized DEWALT
service center. To locate a DEWALT service center nearest to you, call 1-800-4-DEWALT
