Hi my name is Robert.....
On many fuse panels a red light will come on to indicate an open circuit, would be difficult for me to say what the fuse is for, I would pull the fuse and see if it is good or not, if it is not good replace it. IF the fuse is good I would get a test light and see if the fuse has power, if it has no power then I would check the connection on the backside of the fuse where it hooks up. It also could be a wiring issue on that circuit.... Hope this helps, IF you have more questions or concerns please feel free to contact me... Robert
If you happen to find out which DC circuit is not working please let me know as I might have some more input on this... Follow ups are included, I am around daily and respond when I can...... Robert
