Re: Dead Batt (poss. Alternator?)
Likely you did this already but check fuses in power distribution box near battery (likely two 60a fuses for alt in there). Additionally, was alternator regulator tested or was alt "full fielded" for test. (regulator failure will prevent power made at alt from reaching the battery). Also, check continuity of leads going to alternator to make sure they're OK.

THAT IS ODD UNLESS THE TRUNK HAD BEEN OPEN/ CAR SITTING & WEAK BATT DRAINING W ELEC SHORT. NO PUN INTENDED! OPEN THE TRUNK & TRY AGAIN., DONT THINK IT WILL, BUT IF NO START CK BATT CONN , BOOST.& HAVE BATTERY ,ALTERNATOR CHECKED ALONG W/ PROPERLY HAVING IT CKD FOR ELECTRICAL SHORTS. if IT WAS SITTING AROUND A WHILE WITH THE TRUNK AJAR,CLOSE THE TRUNK BOOST IT, RUN IT TO RECHARGE THE BATTERY BY ITSELF (20MINS) SHUT IT DOWN, RESTART CK LIGHTS,HORN, ETC. ALL WELL YOU GOOD TO GO. NO START AGAIN THEN THERE'S AN ISSUE W/ THE BATTERY & POSS AN ELEC SHORT.. GOOD, FRANK M
Even with the wire removed, are you saying it goes dead while driving or just sitting . if it goes dead wile driving then the alternator may not be charging the battery as you drive but if it goes dead while the car sits then there is a draw some where. if you sent me the year make and model with the engine size and also let me know when it goes dead in 1 hour, while driving or car just sitting and i will help you solve the problem. good day
TAKE BATTERY TO AUTO PARTS STORE FOR A LOAD TEST PROCEDURE, MAKE SURE THE CASE IT IS PUT IN HAS THE DOOR CLOSED FOR YOUR SAFETY, BATTERIES SOMETIMES DO "EXPLODE" AND ACID FLYING IS NOT GOOD. IF BATTERY IS NOT GOOD, I WILL SUGGEST YOUR BUY AN AMPHOROUS SOLAR POWERED BATTERY CHARGING PANEL, THEY COST BOUT 30 BUCKS AND WILL KEEP YOUR BATTERY CHARGED UP OVER LONG PERIODS OF TIME.
It sounds like the Alternator is bad or isn't charging teh battery completely. Or if this is the same station that has been selling her batteries they have a bad batch of weak batteries. Have the battery tested for dead cells. If there are none then put it on a charge and fully charge it and test the alternator. Auto zone can test both and will do so for free but you will have to remove the alternator for testing.
If this happens while driving, you have a charging system problem. With a multi meter connected to battery(red+ black-) check alternator output, it should be 13v or better.
If it's dead after sitting a spell and your batt. is 4-5 years old, it may be time for a new one.
Also you might have a draw, (somthing stays on) use a 12v test light, disconect 1 batt. terminal and clip 1
end to the terminal and touch the other end to batt.
post. With everything off,(remove bulb on hood) key
in your pocket, see if test light comes on.
If it comes on you have a draw. pull 1 fuse at a time
(remove+replace)until light goes out.When it goes out
the last fuse you pulled is for the circut with the draw.
If you have any aftermarket electronics radio/alarm/ or
remote starter check them 1st.
Also most auto parts stores napa/advance/or autozone will test your battery and alternator free.
Hope this helps. Good luck
