Question about Electronics - Others
I'm not sure what
AVR = (automatic voltage regulator?)
You could try to excite the generator pg.7
Check the brushes pg. 7
Check the capacitor
Other than that you could open the box where the outlet is sometimes the wire breaks off or comes loose even if its new. Good Luck

AVR Voltage Adjustment
This bulletin covers the following Champion Power Equipment models:
C46535 C41150 C41365
C46540 C41155 C75520E
C49055 C41255 C71350E
Note: Read instructions completely before performing service.
1. On the end of the generator locate the round yellow cover held on by two 7mm bolts.
Remove the two bolts and the yellow cover will come right off.
2. At approximately 7 o'clock you'll see a kidney shaped electrical component called the AVR,
which is held on by two 7mm bolts. Remove the two bolts but do not disconnect the wiring
and turn the AVR over so you can see the backside. You should see a round part coming off
the AVR, this is the capacitor. You should also see a small rectangular box with a jewelers
screw, this is your voltage adjustment screw.
3. With a flat head screw driver turn the jewelers screw counter clockwise and this will lower
the voltage. As the screw is turned back watch the volt meter to see adjustment, the
generator must be running to do this.
4. Adjust the screw until the meter reads 250 volts. On model C46540 when the toggle switch
is turned to the 120 side the volt meter should read around 130 volts. Optimum voltage is
5. If voltage does not decrease or does not hold a steady output please contact Champion at
877-338-0999 for a new AVR.
