fuse panel will light up when fuse is burn or taken off panel, but some will not light up. also I test the current in the fuse connection and one side is giving me 10.5v and the other side 12.8v. can you tell me if this is normal?
The fuse LED will light with a blown fuse or if you remove the fuse. The LED may need an active load to light, yours that don't light may go to a fan or light that is turned off. Works great when you're sitting in the rig, everything is working and then the lights go out. When you go to the fuse panel, only one of the LEDs should be lit.
Measuring voltage at the fuse clips (blown or missing fuse) doesn't tell you much. One side should give you the battery/converter voltage the other side is some combination of the loads voltage drops of that circuit.
