generator is honda gx390, 6600w / surge 8000, northerntool pro series 8000, unit has
total running hours under 30.

had it connected to load and suspect the ground post connection wire was not properly
connected to post at other end, ie. bad ground connection may have caused it to turn
off.

after running it on about 2000-2500w load for 30 minutes, lights flickered inside
couple times and then shut off, there were no motors running or starting at the time,
just couple inside lights, fridge, tv and radio, small a/c unit which uses only 1000w,
nothing else was running.

when I ran to the generator, could detect a faint electric burn odor and now suspect I
may have damaged the automatic voltage regulator.

it restarted fine (I did not reconnect to load) and I got 240/120 output voltage from
the connection plug but did not want to put it back on load for fear of making things
worse (?)

is the AVR easy to diagnose and replace? how sensitive are the hondas or generators in
having the proper ground post connection, if that was the cause of the shut down?
