I don't have a converter with lights that come on when a fuse blows. Does anyone know how the light is wired?
I suspect the light is simply wired across the fuse and when a fuse blows due to a short, then 12v is present across the blown fuse. If you just pull the fuse with no short or heavy load in the circuit, or remove the short after the fuse blows (as the OP did), there is no voltage across the fuse socket and the light would not light.
To check it out you could pull the fuse, recreate the short, and see if the light comes on.
Don't forget to remove the short before plugging the fuse back in. :S
Just my $0.02 worth.
My intuition tells me that there is a sensor and/or relay that provides power to the indicator lamps.
