To check if a fuse is good without a multimeter, look for a visible break or a blackened, cloudy appearance in the fuse wire. Another method is to swap it with a fuse of the same rating from a working circuit and see if the circuit starts working again. Always ensure the power is off before checking or replacing fuses.
