No power at outlet tore it part way apart looking for the brushes but dont want to go any further or will have to crack crankcase open now im wondering if this model even has brushes Power went completly out at once no hit in miss wasnt under load at time just started after some downtime sitting in our shop
I'm getting reference that it a Gentron GG3500 which has brushes and an AVR.
With producing some voltage indicates that rotor is still partially magnetized at least. Note some will cost nearly as much as replace to whole generator.
Common Problems and solutions
SOURCE: Generac portable generator doesn't produce power
Remove front cover on the genset and you will see the brushes and rings. Clean the rings if black with emory cloth and inspect brushes. Flash the fields by apply a 12V battery to the brushes. the brush closest to you or the bearing is connected to the positive side of battery and the back brush is negative. You have to do this with genset running. You should notice your voltage climb up to over 50Vac maybe even over 100Vac. Make sure to use rubber gloves when flashing fields and keep hands away from rotating parts. if voltage does increase when flashing the the voltage regulator is shot. If voltage does not climb then you will need a new genset or generator end.
SOURCE: engine runs but no power aat outlet????
Start with brushes and rings. Make sure your rings are clean and the your brushes have a good length. Flash the fields with 12V battery. Apply positive to the brush nearest the bearing and negative to the back brush, while genset is running. Use rubber gloves when doing this and keep hands away from rotating parts. You should see the voltage climb when you flash the fields. This would mean that you need a voltage regulator. If voltage does not climb, then you will need a new genset.

Bad capacitor. They cost 13 bucks. Call 800-445-1805 to buy one.

there can be many reasons. need more info:
Is it Inverter typr generator?
measure output voltage - anything?
take back cover off generator itself, measure continuity of stator and rotor, and visually inspect windings. You'll find AVR module there too, it may be the reason.

engine starts & runs but no power.checked breakers ,theyre not tripped
