I don't have a/c heat or electrical power,how do I reset the generator to get these things back? Where is the reset button

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.

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: generator motor runs fine, not getting electrical

You may have a bad cap or two on the inside

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. http://www.mcphersoncontrols.com/html/mcp_products/voltage_regulators/MTS63-4.html
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.

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,
