Re: Gravely 816 putting out 40 volts!
It's tucked in the lower left rear of the engine behind the flywheel (which I believe has to be removed in order to get at it). The Onan part number is 191-0886. New Onan replacements are supposed to be pretty expensive (~$200-300). Some have replaced them with 20 amp Kohler rectifiers, and installed, and rewired them behind the dashboards.
