Electrical Problem 2004 Doublecab

[rhodder]

I got an 04 doublcab that the battery dies in if its left sitting for a few days. The battery is only a year old.
All this week I have been working a lot and only drove the truck to work and home all week (about 2 miles each way). Tonight It just barely started, I guess I having been driving it enough to get a full charge. So it was like having it sitting for a few days.

I was away for 10 days this summer and it just barely had power enough to start. I was away for 2 weeks over xmas and it would not start without getting a boost.

Any ideas on how to or best start to track down whats causing the battery to drain.

Only electrical accessories are a set of fog lights, alarm, and nav system (but it was doing it before the nav install).

well it definetly sounds like you have a parasitic drain, I'd invest in a digital multimeter. It could be many things that are causing the drain on the battery, the battery cable may have corrosion, the battery may have dirt, acid, water, contamanants on the top causing electrons to be able to travel across, there could be a short to ground on a simple little light such as glove box light causing it to stay on when you close it. Just do some searching and investigating and i recommend getting a multimeter, it well come in handy for much more than just this.
