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.
Why does my Chevy Silverado battery drain so fast?
The resultant 3.5 amp draw/load on the battery could possibly discharge the battery to the point where the battery will not have sufficient amperage to start the vehicle. This is one of SEVERAL and various years.
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.
How much does a Chevy Silverado battery drain?
If you use a test light, it should light up for a couple seconds & then go out IF there is no draw. As far as how much of a draw will drag your battery down, depends on how good your battery is. As little as 1/4-1/2 amp draw will drain a marginal battery.

What should current draw be on Silverado battery?
I checked for draw through negative battery cable and got a similar reading of 1.26 amps average. I pulled every fuse and relay (and let me tell you that it takes a while when you do it by yourself and have to check each one individually!!!) and narrowed my readings to the following (listed as apparent current draw after fuse removed and left out):
