Practical Uses of Continuity Testing

What happens here

Continuity testing is a quick and effective diagnostic tool. It is particularly useful for checking components like fuses in hard-to-reach places (e.g., in a car's fuse box or a furnace control board) where visual inspection is difficult or impossible. It can also be applied to any electrical component where you need to confirm an unbroken electrical path.
