Question about Cars & Trucks
Do you know if the alternator is charging on the car ?
Its possible the circuit between the alternator and the battery is open, such as a blown fuse.

How long did the 2nd alt. last before it died? The voltage regulator is, I believe, attached to the alternator. Have u had the voltage regulator checked?

Check the large fusible link labeled ALT in the under hood fuse box. If this fuse gets blown, the alternator wont be able to charge even if it IS new,because the ALT circuit is open.

SOURCE: possible bad alternator?
I went through three alternators before we found a good one for our saturn sl2. Now she has been good for two years. All I did was go back to where we bought it from, they hooked up the alternator to a machine and gave us a new one when it read that it was faulty.

SOURCE: Battery keeps going dead
Hello raiderfan520....Have the battery "load tested" this will tell ya if the battery is defective, one bad cell will draw the others down. If it's bad and only 12 months old you should have warranty left. (free replacement or pro-rated)...If your battery load tests OK, then you have an amperage drain going on while the vehicle is parked.
This is called a "parasitic drain"
Make sure no interior lights, under hood, trunk lights...etc. are remaining on. I hope you don't need the following information i'm about to give you, but here are the steps to locating a parasitic drain.....
PS...what kind of season are the raiders going to have this year? I'm in LA county and "Manny being Manny" has turned me away from baseball for now.

What is the voltage you are reading? Is it below 13.2 or so? Also have you checked the current with the engine off to see if something else is working that should not be on. I ran across this twice while working on a truck and car. A relay that was wore out keep trying to close and would drain the battery every couple of months. Sometimes you can hear them clicking or buzzing. Touching them sometimes they are warm or real hot. But that is not a sure sign it is bad. In my Trailblaze they get hot but are ok. Another thougth is the belt on your alt, correctly set to spin it at the right voltage. I have ran across this many times lately with serpatine belts.
