The capacitors look okay. I have yet to figure out how to open the box that houses the circuit breaker wiring. The Briggs motor runs fine. Any trouble shooting ideas are welcome. I really don't like the idea of ordering a new generator to bolt on until I know that is the problem.

Is the Output switch in the "ON" position...the switch is normally on the Outlet manel

There are a few scenarios that can cause this.
1) The extension cord that you are using is too long / too light of a guage. Try a heavier extension cord, or plug directly into the generator.
2) The alternator has lost its "residual magnetism" and may need to be reflashed. Consult Northstar for instructions and details.
3) The voltage regulator (actually a simple capacitor) may be "weak"
4) The diode for field winding may be bad.
You can get a copy of your manual here, page 40 has diagram and part numbers.

Breakers could be bad, but no power to all the plugs, including the 240vac plug indicates something else going on. Either residual magnetism has been lost (has it been a while since it been ran?) and needs to be flashed, capacitor or diodes in regulator are bad, or there has been damage to the rotor or stator. There could also be a problem with the brushes on the rotor as well.
Also, if engine is turning too slow, the alternator may not kick in as well. Make sure that you are turning either 1800 or 3600 RPM, though it is a little hard to do this without electrical output. You might try playing with the governor while a lamp with a sacrificial incandescent bulb is in it. If the engine speeds up, and the bulb lights, then governor needs to be adjusted.

I been using gen for over 20 years on my farm as backup for my solar system and one issue the haeds...many users forget or no one tells them that they need to adjust the heads after every 40-50- hours and any changes in the setting will not allow the grn to start ot it will run for a few seconds than die...look for the exact seerting of the in and out and check tghem and see if that help...good luck. remmber in winter you need low grade oil not high or use synthatic better.
