Hey I've had this problem a few times in the last few days now. I will be driving and out of nowhere my car will stall (when im accelerating usually into 2nd or 3rd)...I think it is the battery becuase it will not start back up w/o my battery jumper or a jump, the engine will just turn over. So I know I need a new battery, but since it is stalling during normal use wouldn't thatalso mean my alternator is not powerful enough?

do you have any amps in your car?

a dead battery will try to recharge and if its really dead/bad it will just become a load that the alt trys to power. i would start with replacing the battery, but it might be the alt.

Could be your alternator too?
If it isn't charging the system, your car is running off the battery only. So once your battery gets weak, your car could die.

Happened to me once, My alt died and I was trying to get home so I could just replace it myself. Well the car used up the last of the battery power, and the car just died. That day sucked...

Yeah I have a Kenwood 600 watt going to 2 12" W3's and a Kenwood 280 going to my Kappa's.

Chris are you saying my alternator could be totally dead and i am running solely off of the battery?

BTW I went to autozone where they checked the charge on my battery and they said I needed a new battery becuase it wasn't holding a charge for as long as it should. (I am getting a new battery tomorrow afternoon)

that's what happened to me, I was running off the battery until there was no more battery to run off of. My own fault, I knew the alt was acting up and I tried to make it home.

I would get the charging system checked, just to make sure that is also part of the problem.

sounds like a bad alternator to me as well

Well the problem has taken a weird turn. I ended up getting a new battery (needed one anyways) which didn't really solve the problem...here is what has happend the last few times.

I was driving on expressway going about 70 and all of the sudden my tach dove from about 2800 to about 1400 and I felt a huge drag. After about a second it went back to normal.

And also today i was engaged in drive but stopped at the taco bell drive thru and i stalled, but was able to start right back up.

The only things I can think of that it could be is a fuel problem (fuel injector? filter?) or an electrical problem. If it was the alternator, how could I check to make sure?

just take it to a shop and see if they can do an electrical test, and see if the alt. has any output.

If the alt turns out good, you can at least mark that off the troubleshooting list.

The same place that tested your battery can test your alternator (given that it is in an accessable place). If that turns out okay, buy some fuel system cleaner and run that through a tank of gas.

again, the engine acting up and the gauge cluster going haywire is a classic sign of a bad alternator.
