Generator Schematic

Why is My 2500 watt generator not putting out AC voltage?

I have a generic 2500watt generator that I was using during Hurricane IKE!
This generator was putting out ac voltage one minute and worked for 2 days then it just stooped putting out any AC voltage the next day.
I thought it might be the breaker on the gen. but it checked out OK mith my multimeter.
I don’t know that much about brushless generrators,
so if you have any suggestions or a website I could go to and find a Schematic or diagram of a Brushless Generator so I might know what to start checking out I’d really appreciate It!

Thank You!

Check the rectifier diodes which are in place. These may not be working.

HHO generator tested with pulse circuit and without.
