Circuits which become overloaded will blow the fuses in question and disconnect any associated devices. This is the most common sign that a fuse box is faulty. A burning smell will often indicate that the fuses are burning out and further evidence will be present in the form of burn marks on the fuse box.
Touch the bare metal on top of each fuse with the test light’s probe. If the 12-volt test light illuminates, there is current at that connection. Touch the bare metal inside each fuse holder if you are looking for a spare fuse location that has a current.
Due to the way fuses are engineered, the likelihood that a fuse would become faulty without blowing is pretty slim, but there are rare instances in which a fuse might appear completely fine, even though no current runs through it.
Listen for the multimeter to beep continuously as you hold the probes against the fuse. If you don’t hear any noise coming from the meter, then the fuse is blown and should be replaced. If you’re using a digital multimeter set to measure resistance, touch the probes together to get an initial reading.
It typically costs $1,000 to $2,000 to replace a fuse box with a circuit breaker. Occasionally, it can cost more, especially if you need more electrical services.

Whilst it is easy to visually inspect the element in a glass fuse to see if it has blown, the majority of fuses have solid, non-transparent bodies that hide the element from view. To test if the fuse is blown, we require a multimeter. Once configured, a multimeter can measure the resistance of the fuse element.
a fuse blows to keep current from going through the circuit. in other words, there’s no way a blown fuse can drain the battery. take the battery in to get checked, it might just be a bad battery.
