4 bad batteries in 4 months, what gives?

Well, the car sat overnight and fired right up this morning. So I'm ruling out any kind of short or constant draw on the battery.
 


WTF:th_angry-censored:

New alternator and new battery installed a week and half ago. Go out this morning and my car was a damn paper weight. Granted it has sat for a couple of days, but my battery charger wouldn't recognize it was hooked up. So I take it out up to O'Reilly's and their tester keeps saying "check connection" when it was hooked up. The guy working just said it was bad battery gave me a new one and off I went.

I have now checked all my grounds, connections, and even pulled apart my dash to check my stereo connections. When I installed my Alpine head unit I bought all the harnesses needed, so I didn't need to cut any wires. The only thing I did different was hook up some ground wire to the stereo, that was grounded to factory head unit.
So the saga continues.
 
Status Update: Problem Solved (so far, so good)

The new alternator didn't solve the problem, :mad: so I start looking elsewhere. After a long time of searching and no luck with finding bad wiring, I finally decided to pull the "radio" fuse and let it sit. And I'll be dang, no dead battery.

Now just so, everyone is on the same page. I have the Bose radio and it is supplied by two circuits. The "radio" circuit is a 10A circuit and only supplies the "switched" 12V. The other circuit is the "Amp" circuit, it's rated for 20A, and supplies the "constant" 12V.

So my problem was with the switched 12V circuit, which totally surprised me. After looking at the schematic, this circuit has to runs. One that goes straight to the radio and the other goes straight to the OnStar unit in the trunk. Once again a dismantle my dash to get to the wiring and nothing looks questionable. So I decided to rewire everything and see what happens. At this time I decided to just hack the harness and take out all the "Factory System Adapters". Got it all done, everything working good. Put a DMM on the battery at got 12.4ish volts, let it sit overnight, got up this morning and still had 12.4ish volts.

So I'm thinking the problem was in the wiring of the System Adapters, which was a PIA to fit behind the dash anyways. I don't really feel bad about not using them, because I got them free as part of some promotion. But you would think they would have a little better QC. I assumed they were good and they were what causing me problems the whole time. Oh well, lesson learned.

damn, u sure have some patience. i'd beat that mutha to death!!!!!that kinda stuff really tries my patience. i have to sit back and think it thru or i'll get too aggrivated. i also work around this field too. how ironic is that sh!t?
 
Two weeks and still no hint of a starting problem. I knew I should of just hacked the harness to begin with, but I was trying to get around having to do that. Oh well, just proves the simplest method is almost always the best method.
