Just as a follow up, for those interested, here is a copy from owner's manual, in regard to starting the gen, and the second part is my reply from Champion Customer Service.
Page 18 from manual
Starting the Engine
1. Make certain the generator is on a flat, level surface.
2. Disconnect all electrical loads from the generator. Never
start or stop the generator with electrical devices plugged
in or turned on.
3. Turn the fuel cap vent lever to the “ON” position.
Customer Service response:
The control unit should only let power out with the power output light is solid meaning everything is as it should be.
If the idle becomes inconsistent, like the machine is starving for fuel, it will go into overload and cut power to protect what is connected to it.
When the machine is first starting the output light will blink and won’t supply power until it is fully initialized.
However, it is still considered best practice to start and stop the machine with no load attached.
Respectfully,
Champion Power Equipment, Inc. | Customer Service
The green output light they are referring to is a small green LED displaying the receptacle. While I specifically asked if okay, to plug my RV cord into live receptacle of running generator, no mention about RV cord OK, in response.
Champion does reply within 1-2 days from email sent, and does have a real person to call/talk to about technical matters.
