No, it's unlikely that a blown fuse is draining your battery. A fuse is a conduit for electricity. A blown fuse will simply stop a headlight or turn signal from functioning. In some cases, it can lead to an open circuit that draws energy.Even if you have all of this, they shouldn't drain a battery in one week. Only thing you can do is to get a Ampere Meter and stick it in that faulty fuse to see what it drains. The fuse can not drain anything, it must be the wires or the device that the fuse is for.

Can a car battery drain in a week?
As mentioned above, there are many components in your car—like clocks, computers and security alarms—that continue to draw power from your vehicle when it is turned off. This is called key-off battery drain or parasitic drain, and it could cause you to wind up with a dead battery after multiple weeks with no driving.

Can a blown fuse cause a parasitic drain?
A blown fuse will simply stop a headlight or turn signal from functioning. In some cases, it can lead to an open circuit that draws energy. Other causes could be a malfunctioning fuse, leading to a parasitic drain on the battery (think of a glove box light that won't turn off).
What is the most common cause of an excessive parasitic drain?
Several things could be causing problematic parasitic battery drain, including short circuits or electrical devices that remain energized, including: Under-hood or glove-compartment lighting. Headlights. Computer module.
Can an alternator drain a battery overnight?
Since the alternator isn't generating vehicle electricity, the problem component pulls from the battery, slowly draining it overnight until your vehicle won't start.
Do alternators fail suddenly?
