2002 Chrysler concord alt light came on battery went dead car died jump it, started died when took off jump cables replace battery , cleaned conections starts up alt light out left set overnight sart

wow test the alternator next, 11 to 15vdc less is bad ALT(AT BAT TERMINALS LUGS)
find a shop that can do electrics.
keep and open mind.
say will not crank , not will not start or answers WILL BE WRONG
so it started and they did not once check all fuses and the alternator
if they replaced the ALT and did not remove the NEG lug from the battery then the blow up the 100amp huge alt fuse
making alt dead forever.
or the other 3 alt fuses blown.
find a real shop with real ASE techs,

also learn that ALT can short one of its huge internal 3 phase DIODE
and now the ALT I HUGE NASTY NOISE GENERATOR AND LAMPS FLICKER AND ALL COMPUTER IN THE CAR GO STARK MAD.
WE SCOPE THE ALT TO SEE THAT HUGE NOISE ON THE BATTERY.

BAD ALT i BET.
THE WORST FOR HE WORST.
OR BAD GROUNDS TO ALL THAT.

1 Battery completely dead. check and replace if bad.
2. Check all battery cables at both ends. Clean and tighten.
3 Check all fuses and circuit breakers
4 Check alternator output. not over 13 volts replace check alt belt tighten
B4 buying a batt or alt make all the checks and test after each one for power/start

I am a strong believer of the KISS therory, so lets start on the most likely. When you replaced the battery, did you also clean the battery cable connections? If not that is the most likely cause! If not, suggest you get jump your car to make sure where the problem is. If it starts with the jump start then it is in the battery system - battery, battery cables, alternator.

Make sure all connections are clean and tight, belt is good and have alternator (charging circuits) checked. Sounds like alternator may be defective.

check owners manual for blown alt fuse

It sounds like a bad connection in all honesty. if you havent replaced terminals do that. any corrosion you should clean check the cables also and see if they are corroded ander neath the coating I have seen terminals that were pretty tight but yet not enough to crank. I truly believe that is where your problem will be found. please let me know.

the battery is located under the rear seat, check battery connections. if connections are tight replace starter.

If u have plenty of power in the battery, then have someone check the timing belt........Anthony

so my 06 cobalt keeps dieing and i have to jump it alot lately is it my alt or my battery

Clicking??? Probably starter/alternator. does the starter turn? The clicking, is that all you get when you turn the key? Have the battery checked and make sure its holding a charge. If battery holds a charge, its time to have your alternator tested, if the alternator checks, then the clicking may be the starter/soleniod. Places like autozone will check the battery/alt for free, provided you can still drive to get there.
