Your fuse panel may be in similar location to my 99 , but I think I only have the one fuse , as Tom , mentioned .
The fuse is in a 12 volt panel beside the 120 volt circuit breaker panel in the bed room , and for some reason , labeled " Wrap Lights ". I shorted a basement light and found the fuse ; I didn't check the engine and under hood light for operation when the fuse was blown.
EDIT : Correction , the front Newmar fuse panel , shows a 7.5 amp fuse labeled engine compartment .Nothing about under hood ( gen set ) light.
NOW , here's the problem I can't tell you where your panel is located , because I know there were changes to the dash board in 2000.
This fuse panel is to the right of the drivers foot in my 99 and behind a black plexi glass panel,
