Resolved 1G Battery won't hold charge

[Trav83]

Ok I left my lights on and killed my battery yesterday and so I had to have a friend give me a jump, well when I left to go home everything got dim in the car and it just died, so my friend jumped me again, 10 seconds after we take the cables off, the car stalls and dies. My alternator is only 8 months old so I decided maybe it's just time for a new battery, so I went ahead and bought one.

Today when I was going to leave the grocery store, my car wouldn't start again! I got someone to jump me luckily, I just barely made it home, as I pull into my parking spot I could tell the car was close to dying. Ok so I have a brand new battery and a 8 month old altnator, what is the problem?! Why is it not holding a charge?

Dammit, everything was fine until I had to go and leave my lights on

Have you tried making sure you have a solid connection? If you don't have a good connection the alternator wont' be able to charge your battery accordingly.

Your alternator is not charging. I would have it tested. Check your fuses.

I had this happen to me before and it was the alternator fuse that went out. But if that's still good i would get your alternator checked.

Ether Alternator isnt charging it


or check your terminals on the battery.. mine were really corroded so i used a wire brush, brushed them off real good and it held charge

Yea check your connection and fuse box to see also check your belt maybe it came loose

check the charging voltage with a dvom/dmm. charging voltage should be 13.5-15v. if this is not the case, check the alternator fuse, battery fuse, terminals at the battery and alternator for loose connections or corrosion. also check the ground at the battery and any other related grounds for high resistance (greater than .5 ohms)

Battery terminals are tight, battery ground wire is good, alternator fuses are fine, battery fuses are fine, alternator connections are fine as well. I guess tomorrow I'll have them test my alternator, I just don't know why the alternator would go bad from killing my battery..

wow i litterally just got back from autozone for the exact same problem. He told me the old dead battery could've taken out the altenator with it. Which is what happened to me with a 2 month old aternator. so you should take it off and go get it checked if everything else seems to be ok.

I took the alternator out and had autozone test it, of course it failed so I received a new one. I realized when I was putting in the new alternator that I had NO GROUND WIRE! and that must be why it went bad
