'95 Chev 3/4 ton battery drain

I have a 95 Chev 3/4 ton PU with a new battery. Something is draining the battery after about a week or so of not driving it. No lights are on, radio's fuse has been removed in case that was causing it. Any ideas?

testing for battery drain

you can try this: with the truck shut off and key off remove each fuse one at a time and put an amp meter across the fuse socket. their should be 0 amps on most of the fuses. If their is a reading however slight you need to determine wht is causing the drain.

usual suspects: glove box light, a dash light somewhere, accesories wired in like a cb radio, cellphone charger, even without a phone plugged in.

and the obious question is, have you tried a new battery?

Maybe the new battery is defective.

Rex,

An auto pro can correct me on this but I believe that all or most computer controlled fuel injected engines normally have a small parasitic drain on the battery.
I am actually going to replace the battery on my 95 Caravan this morning for this same thing.
Battery will start vehicle fine, even in our now sub-zero temps, except if sitting for longer than a day.
This is easy to diagnose with a battery drain tester.
