The fuse can not drain anything, it must be the wires or the device that the fuse is for.
Can a bad fuse cause car battery to drain?
Other common open circuit causes could be due to blown fuses, faulty switches, faulty relays or poor connections. In some cases a shorted circuit can create a parasitic drain causing the battery to lose its charge.
Can a fuse cause a battery to drain?
The fuse by itself cannot drain the battery. It’s just a place in a circuit, in series that limits the amount of current that can burn the wiring up and starting a fire if a device downstream of it, or a shorted wire would try to pull too much current from the battery through that circuit.
What can drain a car battery when the car is off?

What would cause a battery to drain overnight?
This can be a result of various factors including the number one cause which is leaving headlights, glove box lights, or cabin lights on overnight. Parasitic drain can also be caused by defective fuses, bad wiring, and poor installation of a new car battery.
Can a blown bulb drain car battery?
It wouldn’t be the bulb. A blown bulb is an open circuit. Alarms don’t use much juice at all to run. They do draw off your battery but it’s using just enough juice to flash that LED, which is next to nothing, certainly not half an amp.
Why would a battery keep dying?
Some of the most common reasons for a car battery to die repeatedly include loose or corroded battery connections, persistent electrical drains, charging problems, constantly demanding more power than the alternator can provide, and even extreme weather.
Can a blown bulb drain a battery?
No, it will not drain your battery, the circuit is not complete with a burnt out bulb.
Why does my car battery died after sitting for a few days?
A car battery that dies after sitting for a few days will either need replacing due to age or be suffering from a parasitic drain. A badly wired radio, a faulty relay, or a phone charger left plugged in could all be drawing power from the battery while the car is sitting.
Why does my car keep dying with a new battery and alternator?
Why does my car keep dying with a new battery and alternator? Loose or corroded battery connections, continuous power consumption, charging problems, persistent need for more power than alternators and even inclement weather are some of the most common reasons for recurring automotive battery failures.
