Electrical Vampire drain on a brand new battery
I recently purchased a new battery for my 94 Suburban 1500 after discovering that the last one was installed 3-4 years ago. Since the install of the new battery, I have had to plug the battery into a battery charger so I can turnover the engine, while I am waiting for the transmission parts to arrive. Has anyone seen something similar to what I am experiencing?
BTW - fog lamps are installed but they don't work for some reason. will worry about the fog lamps later unless they are the culprit for the issue that I am seeing.

Something is drawing current and killing the battery.
The best way to track it, is to use a multi-meter on a current scale. Disconnect one side (use the ground, safer) of the battery and insert the meter between the battery and the cable. check the reading to see what the current draw is, start removing fuses.
Remove the fuses one at a time............reinsert the fuse before pulling the next one.
When the current draw falls off to zero, or very close, you have the circuit that is causing the problem.Ray

I had the same thing happen on my 97 awhile back, did what RayVoy mentioned, found the radio was pulling an amp.
Word of caution, remove your meter before opening the door, yank the fuse, shut the door, then check. Opening the door with your meter inline with the battery might draw enough to blow a fuse in your meter from interior lights.
If its your radio, and you don't want to chase the problem (like me), here's a Y-tube link to a cheap solution.
