Thanks for the replies. All good ideas and the general circuit diagram is very helpful.
The LEDs that show a blow fuse work as long as there is a load on the circuit. That makes sense. If there's no draw, there's no current.
I am working with the converter manufacturer on a different issue and they claimed that you will still get current when a fuse is blown. I'm still trying to wrap my head around that one but does anyone want to check their own? Yank the fuse on a circuit with a multimeter attached. I used a light fixture, multimeter probes held in the bulb socket by themselves.
