I am having a very irritating problem with my truck. Every week or so something is draining the battery (which is 3 months old I might add) and the truck just will not start. I don't drive the truck very much anymore as I am in a carpool to work, but it does get driven everyday nonetheless, just not long distances. I always allow for a 10-15 minute warm up before driving and it has left me stranded more than once. My cousin who is a certified mechanic has tested everything under the sun and still cannot figure out what it is. Anyone have this issue or have any idea what it could be?

If it's a substantial drain, remove the negative Bat terminal & read voltage between Neg Bat post & terminal connector. While you're monitoring that, have someone else pull fuses one at a time. When you pull the fuse w/ the draw, the voltage reading will drop. This will at least isolate the circuit involved.

Other possibilities is a connector that appears clean & secure, but is not, or a cable that is compromised by corrosion hidden under the insulate sheathing.

I'm with Ymeski with the corrosion...also check your frame ground and your starter ground. a short to ground will cause a drain.
