Engine runs fine but probably overloaded the generator. Is it just brushes or coil too.

this
engine dead.
or good and welder side dead
buy the service manual from Lincoln??

Yes, it can.but how is the airflow over the engine? If the air is being blocked, that will overheat it too.

Red muffler? that can be caused by restricted cooling airflow over the engine, excessive carbon build up in the cylinder, and also way too lena a fuel mixture. Also be cautious of engine overloading

Hi:

Probably your machines just overloaded; the engine will run and produce voltage but no weld output. Check your fuses F1 and F2, if they are open replace them.
Both fuses are located at left hand side of machine, open it and you will find them on the bracket.

Good Luck.

If this was useful please vote, thanks.

Take a resistance reading across the brushes with and Ohm meter. (not running) You should read a low resistance. If you have no resistance across the brushes then then either the brushes are not mating with the armature or the the armature is open.
IF you have resistance then the AVR (Automatic Voltage Regulator) in the endcap has failed. With the engine running and the Brush block disconnected you should have 4 - 12 VDC on the two wires going to the brush block. No voltage = bad AVR.

Thanks for choosing FixYa.

You may have overloaded it, and it may have been damaged.

Check your circuit breakers first. If there was an overload, they should have tripped if overload was long enough in duration and high enough in capacity.

If the breakers are good, then check your diodes and capacitor regulator in the end of the alternator. While you are here, check your brushes as well.

Do you have a manual for your generator?

The problem might be with your eyesight. This small generator produces a maximum output of 650 watts. Any hairdryer uses way more than this, as you could see it on the label.

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.

This sound like a loss of residual magnetism in the generator. The field will need to be "flashed".This is also known as re-exciting the field of the generator.
The Coleman manual gives these steps:
1Use a 6 Volt lantern batters (dry cell) or a 12 Volt automotive battery.
2.Disconnect all loads from generator.
3. Remove the brush cover (that's the rectangular plastic cover on the end of the generator.)
4. Plug a lamp or light into the generator before starting the engine. The light will illuminlate when ?Voltage has returned.
5. Start the engine with no load connected to the generator.
6. Attach the "-" lead of the battery to the negative brush. Very briefly touch the "+" lead of the battery to the positive brush. Remove as soon as Voltage builds up.
