Can a fuse kill a battery?
The fuse in and of itself cannot be the cause of the power drain. It is, however, an indication of where the power drain is coming from. If by pulling the fuse you get a noticeable drop in battery drain, whatever is causing the drain is on that circuit. in other words, there’s no way a blown fuse can drain the battery.
How do you know if your GMC truck battery is dead?
One by one, pull each fuse in your fuse box. Check the multimeter after each fuse pull to see when the amperage draw goes away. Once you find the fuse that causes the amperage draw to go away, you at least know what circuit the draw is coming from.
How to drain a battery on a GMC Truck?
With key off, unhook your positive battery terminal. Put one multimeter lead on the battery terminal and the other on the positive cable. You’re basically making the multimeter part of the circuit. Set the meter to read amps. Now, since its being drained I assume you’ll see some kind of amperage draw.

You go out to your car and the battery is dead overnight, this can be frustrating to say the least especially when you are late to work or got the kids ready for school and ready to leave. When the battery looses its charge in the morning you could have a voltage drain in the electrical system which is called a parasitic draw.
