    Hrmm, strange, I always run the generator at 60Hz from start up as you recommend on your site, so I do not think that would be the cause. Are there any other common causes of the voltage regulator panel breaking?

    I think I found the issue. I opened up the control box and took a look at the voltage regulator on the left side and found that component C11, line 17 of the voltage regulator board was fried and had bubbled out the side of it. In Figure 6-4 of this manual,

    you can see that in the DC voltage test, this component is part of the circuit that you test.

    Just checked it with a multi-meter, the convenience outlet is outputting 60 Hz, but only 2V. The Hz meter on the generator is still all the way to left though. The convenience outlet breaker is not tripped either.

    Also, I opened up the electrical side panel, and can smell that the burning smell was something electrical in there. I can’t find any burnt areas from a shortage in there though.

    Also, not sure if this detail matters, but, all the symptoms are the same when running on the 120V mode and the 120/240 mode.

    So, it seems like the engine is good, and that it is something with the electrical components?
