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...

Just my $0.02 worth.
My intuition tells me that there is a sensor and/or relay that provides power to the indicator lamps.

No sensor, No relay, just the LED and a resistor wired across the fuse.
YES, if you measure the "Fused" terminal voltage with no fuse and no load it will be not 12 but 10 volts on many meters.
But if you put the slightest load on it it drops to zero very fast.
This has been a standard way of wiring blown fuse indicators since before I was born.. You use a SMALL light (The LED only passes a few mA) (few/1000 amp) so it is 100% safe to do it that way.
If you touch the fused terminal with a wet finger you won't even feel the shock the current is that low.
