Honda 3000is powering a 1999 American Tradition

That is one monster charger, but I can't imagine it actually drawing 23amps. That would indicate a charge rate of somewhere around 200a! That said, it appears it is drawing that much.

A couple things: does the generator surge/sputter then give up and turn on the Overload light? That definitely says it's too much for it.

Can you turn down the charge rate on the charger? Perhaps there's an "Ac breaker size" setting like on my old Prosine unit.
