Admin Can a blown fuse make your tail lights not work?
A blown-out fuse could cause your tail lights not to work. The car fuse looks similar to any other fuse out there. To check this component, you need to locate the fuse box first. However, as you inspect the fuse box, switch off the car ignition.
How can you tell if a fuse is blown in your car?
A blown fuse will show voltage on one side, but zero voltage on the other side. Voltage drop: Measure across the fuse, using both positive and negative probes. A good fuse will show 0 V, no voltage drop, and a bad fuse will show 12 V, full voltage drop, which means no voltage is available to the rest of the circuit.
