Mccullah fg5700ak generator wont produce electric

SOURCE: generator will not produce electric power

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: 5500 generator stopped producing eletric after

First check with the dealer and see if it is still under warranty. If it is not, make sure nothing is blocking the air flow around where the control modules are located. This could cause the voltage regulator and other electronic parts to overheat. Next check the brushes and make sure they are free of any dust or build up preventing them from making contact.

If everything is OK the next thing I would do is change the voltage regulator.

Hi,
After a generator sits for a time the magnetic field can go flat....then the generator will not produce any electric...

Here is a link that will give you some background and a couple of ways to fix the problem...

generator flashing

SOURCE: Homelite generator model # LR 5500 not producing electricity

I have the same unit and same problem.
I have lost my owners manual. Did you figure out what needs to be done to correct the no output issue.

SOURCE: GENERATOR WILL RUN BUT DON'T PRODUCE ELECTRIC

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)
(Generator OFF!)
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...

Try this.
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,
