What should you check first when searching for an electrical problem?

Explanation:
Start with fuses. A fuse is the first line of protection for an electrical circuit, so a blown fuse is a common, simple reason a system won’t work. Checking fuses is quick, inexpensive, and can confirm whether the power path to a circuit has been interrupted by a fault. If you find a blown fuse, replace it with one of the same rating and re-test. If it blows again, you’ve identified a deeper issue in that circuit that needs further diagnosis. If all fuses look good, then you move on to other possibilities like battery terminals, relays, or wiring, but the immediate, most efficient first step is to check the fuses.
