somthing might be grounded out. but you better hope not cuz that'll be a bitch to find, untill your car blows up.

does the civic have a voltage regulator?

Actually, now that i think about...it sounds like its a dead battery. Although it might show 12-16 volts, the amperage might not be enough to start the car. Take the battery out and bring it to pepboys/autozone/advance auto parts and have them check the battery.

If the alternator was dead, the car would only run for as long as the battery was able to power the car. Remember that the car needs 2 things in terms of electricity, volts and amperage.

or it could be that even though the new alternator is ok, its not juicin the battery because of the connections. did you have the old one tested before you got the new one? cause its free to test. when you hook up the alternator make sure you connect the leads to the right place. i know it can be a pain cause of where the alternator is located. i wanna know how it turns out. if its not recharging it could be that one of the leads from the alternator to the batter is corroded or broken somehow. good luck.

I believe it is the battery I could be wrong though.

OR you can just go to autozone or discount auto and they check it for FREE. Can't believe you changed the alternator without checking.

it's the alternator

to test, start your car with the battery disconnected, then when it is running, disconnect the pos terminal. if the car shuts off or stumbles, it's the alternator. if your batteries won't charge i almost gaurantee you it is anyway. one battery failing to hold a charge is possible, but a double battery failure, especially with a brand new one, is near impossible.

He doesnt have a brand new battery, he has a brand new alternator and the same battery. Unless your battery is a deep cycle, then it's crap because it's been drained completely. You are supposed to replace the battery and alternator together, so I would get the battery checked out.

i will try hooking up a different battery to make sure...and btw we did try and go get it tested through autozone/pepboys/and kragen....but no one had the program or the plug to run the alternator...so i was unable to test..and kragen just decided to replace mine for free neways(lifetime warranty since it's not my fault they dont have the program)...im not that stupid to just change my alternator...without testing....

its most likely the battery...cuz it can hold 12 volts but it wont have enough juice to crank out about 200amps for the starter to work over...just had this problem yesterday with a friends truck

goddie that ur not having my problem..

all dash light just turned on...and i can't start my car..

turns out, after playing around with the stuff inside the car, two fuses blown...and that's when i can start my car again...

doh yeah if you already replaced the alternator, try the battery next and see what happens

amybe it was the battery all along and the alt was fine?

Mystic3030

Battery light only comes on when the alternator is dying...I know, it makes no sense.
