Two suggestions. One: check for voltage from the secondary coil wires (if it has one). Two: unless stated do not do this, I have always flashed the excitor circuit through the 120vac receptical. Give these a shoot and I hope it works for you.

SOURCE: i get no 110 or 220 volt power
generac was purchased by Briggs Stratton some years ago, however some information is available at the following web address, just enter your model number:
The small board that you describe is the bridge rectifier that converts ac from the windings to dc for the armature. You can test the brush/board by removing the part from the generator and applying 12 to 16 volts ac to the input tabs/wires then test/read dc (dc voltage will be lower than input ) voltage at the brushes. Use meter to make sure that you are getting dc. I use a small power supply less than one amp that I purchased at the thrift store for a couple of dollars. If test fails replace part. If it tests ok re-install brushes and re-connect the ac power supply to brush/board which in turn will energize the armature. At this point test the armatrue for magnetic power. I use a thin welding rod or wire against armature. If you feel a magnet start the engine. If the windings are good you should get some voltage at the plugs and the two wires that feed the brushes (will not be full voltage). If voltage is present, kill engine and disconnect ac power supply and connect the original wires to brushes/board and start engine. If you now have voltage at plugs you spiked the system indirectly by energising the armature. If still no voltage you may have an open circuit that feeds the brushes or diode pack is failing with the incresased voltage. Good luck with your repair and email if you have questions.

Cummins P2200, 2KWatt, it starts fine, but after a couple of minutes, it gives quite high voltage output, meter needle goes beyond 300v, engine speed seems high since throttle is increased, indicator light on generator also becomes bright, after a minute or so, things come to normal, sometimes takes few minutes to come to normal, situation is same, with/without output load. this happens within initial 15 minutes after startup, afterward everything is normal.
