Assembly,​​ Holder,​​ Brush 66386GS

Replaced the old parts with the new ones followed instructions that came with the parts . All went well generator now puts out electricity problem fixed. Advice take photo of wiring so everything go's back the same way. Reair was very easy.

I took cover of generator off replaced the avr and the brushes and put everything back on started the generator up and checked it ready to go

1. Removed generator cap using 8mm socket set
2. Removed and replaced old AVR and brush assembly
3. Followed included instructions to remagnetize brush assembly by using small alligator 4. Clip jumper cables (not included) to connect positive and negative leads of brushes to a positive and negative posts of a 12 V battery (not included).
5. Started and ran the generator for a few seconds.
6. Removed jumper cables.
7. Reconnected lead wires.
8. Re-installed the cap.
9. Started generator and now works as good as new!

Turned out the brushes were bad and not sending enough voltage through the system, the system detected low voltage and shut down. It would start, run for 30 seconds and shut down 3 times. No error codes on the panel, just wouldn't stay running.
Because the brushes are at the bottom of this model I actually had to take off the side panels, disconnect all wiring and fuel line and remove the engine. The cap needs to be removed from the alternator at the very bottom of the engine/generator assembly to get to the brushes. Once you have it out, its very easy to get them out and replace them. Unfortunately because of the design and that the generator side of the unit is sunk down into the bottom of the unit I don't believe there is a way to change the brushes with the engine still in the unit. Its also impossible to just remove the generator from the engine as you would need a puller to disconnect it and this can't be done with the engine in place.
The engine is very heavy and took 2 people to lift out from the mounts and move it. If your strong you can probably move it a short ways out of the unit and lay it down to work on it.

Took off cover
Took off old brushes
Replaced with a new set
Replaced cover

Tested AVR by jumping brushes to establish a field. This did not work. R/R AVR but still no output voltage. R/R brushes, idle control, and idle control PCB. Generator works properly.

1. Removed front cover from rotor and stator. 7mm nut driver
2. Removed brush assembly and regulator.7mm nut driver
3. Used pliers to pull wire connectors off
4. Installed new parts.
5. Our front cover back on.
6. Started generator tested power.

1. Remove plastic cap/vent off the end of generator
2. Remove and replace brush assembly, being sure to connect wires correctly
3. Remove the old voltage regulator and booster (if equipped), replacing both items with the voltage regulator as described in the directions included with the new voltage regulator
4. Start generator and retest for proper function (electrical output)

Disconnected spark plug for safety reasons,
Removed cover with socket set
Slid out regulator - AVR control out of slot holding it....
Removed screw holding in Assy Holder , brush...... disconnected wires by pulling them off....
Pulled out assy holder, brush and replaced with new one after plugging wires back on new one , then screwed it back in.
Removed wires from regulator - AVR control, and then plugged those wires on new AVR control
Then slid back into slot ....
Replaced cover, reconnected spark plug....
And now have electricity.!!!!!
