The way the red blown fuse lights work is that when a fuse blows, the current is redirected thru the red LED to the device(s) connected on that circuit. There must be some device connected to provide a source to ground for the current to flow thru the red light. If there is no device currently connected then the red light will not illuminate even if the fuse is blown. Lights are a good example. If the light switch is off, the lights are disconnected from the circuit, and current can not flow thru the light.
Try turning on the light switch and see if the red light illuminates.
