I have a wen 5500 watt portable generator the engine runs fine but the generator output surges from full to dim to no power on a light bulb on both sides any ideas would be greatly appreciated. thanks.
Not sure if this will work, but worth a try. The generator may have lost its magnetism and needs to be flashed. To do this i use an electric drill and run it in reverse for a few seconds, on/off. Works on my old Genrac that i fire up about once a year.
ok thank you I will give that a try.
