put a volt meter on the battery while hooked to the truck, then start pulling fuses one at a time... when u pull one and the volts go up, thats the circuit with the draw.
Good luck!

My guess is that your alternator is going out. Whatever you do don't buy a crappy autozone replacement. There are a couple of places that will rebuild your denso though like new or even with higher output.

But Team420 might have meant an ammeter, hooked in series. That will 1) tell you if you have a parasitic draw, 2) how much, and by pulling fuses 3) where it is.
You should have about 10-50ma of draw all the time (clock, etc.), but that would take about 3 years to run down the battery. If you're running the battery down overnight you've got to be pulling at least 1amp (a 40amp-hr battery, in theory, can put out 1amp for 40 hours).
Don't be stupid; with an ammeter hooked in on the 0-10amp scale, if you crank the starter you'll incinerate the meter.
