Why does my battery cable have a fuse?
Cube fuses at the battery provide protection for the electrical circuits connected to your battery (as well as the battery itself) by eliminating unprotected sections of cable between the battery and the first fuse. A common circuit that uses a cube fuse at the battery is an inverter.

There should be two heavy white wires that attach to the positive side of the battery one goes to fuse box for power distribution the other is the return from alt. There is also a 60 amp alt fuse in fuse box under hood. Make sure connections are clean and tight or battery won’t charge. 7 people found this helpful.
What does a battery fuse block do?
A fuse block provides multiple fuse circuits, usually 2 to 12 spaces. These circuits can be independent, with each having its own individual input and output wires, or ganged, with power shared across all circuits.
How do you know if your battery fuse is bad?
Usually, a blown fuse just causes a minor car electrical problem, like backup lights or interior lights not working, not being able to use your radio, losing a turn signal, or some of your climate control features not functioning properly.

Faulty Fuse And if that’s faulty or the fusible links are damaged, your car wont start. A damaged or blown fuse can prevent power from reaching the starter relay, which is needed to provide the spark, the ignition, and the power to move your vehicle.
Will a bad fuse drain a battery?
3. Electrical Glitches. Electrical glitches in your car and car battery may be caused by factors such as poor installation, faulty fuses, and flawed wiring. These electrical glitches can result in the normal and expected parasitic drains on your car battery becoming excessive and drain the battery when the car is off.
Can a fuse cause battery 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).
Why does my battery keep dying overnight?
A short circuit may cause excessive current draw and drain your battery. Check the charging system for a loose or worn-out alternator belt, problems in the circuit (loose, disconnected or broken wires), or a failing alternator. Engine operation problems can also cause excessive battery drain during cranking.
