Low voltage output on xg8000e portable generac generator voltage is only 103/207

Beware of an adjustment complexity with an new kind of poweroutlet automatic voltage regulator avr , have you measured the generator UNLOADED for 230 volts ?
because it can be normal that 67 volts output changed when you connect an paint heat gun i was surprised a few weeks ago that i get an GENMAC 8000 that is a look a like generator coming from china build . first i was measuring some of the same output AC instead of 230volts.

baried in the motor hard to get to but if you take tank off you should see it good luck

Try putting 12 volts across the commutator at the brushes. Ust a low current battery nor a car storage battery.

Good luck,

check voltage input at voltage regulator, then check output from
the regulator.

Low voltage? how low? Assuming engine speed is correct, first check the capacitor in the end of the alternator housing. Common problem

It is possible that your voltage regulator is shot but before purchasing the volt regulator try flashing the fields first and make sure the brushes and rings are clean.
