Charging Problem

Now this isnt on my PSD but I hope you guys will help just the same. So I have this '97 Blazer in great shape. Every thing on it works great except the dang thing wont start if you let it sit for a while. I have changed the alt, the battery, and checked all the wiring that I can think of for dead shorts. Any ideas?

do a parasitic draw test. Turn everything off and set up an ammeter in series with the battery and start pulling fuses until amperage goes to nothing.

That will tell you what circuit is draining the battery.

Usually the ignition will cause a large draw, so i would be sure to check that.
