Problem with converter fuse panel
I have a barely 2 year old PD4645 converter with the red led indicator lights on the 12v fuse panel that light up when a fuse is blown or pulled from the buss.The problem I have run into is that the i...

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.
The circuit with the blown fuse would have 12v present on the powered side of the fuse but would have a ground on the circuit side of the fuse, That's what caused the fuse to blow. Thus there would be 12v across the fuse socket. Normally there would be 12v on both sides of the fuse since there is a wire (fuse) between the two connections to the fuse.
