Ok, believe it or not you posted most everything I need to figure it out.. I have a progressive Dynamics panel. works same way But it is a "Stand Alone" panel.
First the RED LIGHT (LED) are you sure you are checking the correct fuse? Also sometimes an LED may be there for reasons other than blown fuse indication.
On my PD panel the LED's do not line up exactly and as A result I always have to check TWO fuses when I blow one.
As for the 10 volts
The way the LED's work is like this....
Batt---fuse-----------------------load
Batt---LED--Resistor--------------Load
That to say the LED and it's pass resistor are in PARALLEL with the fuse.
What you are seeing is voltage passed by the LED when the load is off.
Turn the Load (IE: LIght) on and that voltage should go to ZERO unless the light is also an LED.
