I have a 91 accord 4 cylinder. The car died while driving last week. I went to autozone and got a new alternator. Installed it and it died the next day again. I went in and exchanged it because the pulley was loose on the first one. I installed thebsecond one drove for a few hours and my car died again. I put a jumper on it and started the car. Removed the positive battery terminal and it shut off. Now I had this alternator tested when I exchanged the first bed one and it showed it was good. So my question would be is there something else that could be causing the problem or does autozone just keep giving me shitty parts?

Anyinsight would help before I go bitch out an autozone employee.

Thanks,
Coty

 

You didn't say, but did you have your battery tested?

 

Start the car, test the voltage at the charging post of the alt and at the battery....what are the readings?

 

you have to have your battery tested for cold cranking amps .... it may have the voltage but not the amperage. when ur cooling fans turn off they need alot of power to get going nd if you have a bad battery it will make it look like a bad alternator. just my 2 pennies.

 

If your battery is relocated or not, but definitely if it is, remove the ground where it is mounted to the chassis, make sure you have bare metal no rust, and bolt it down very tightly again, it sounds to me like you have a bad ground, car functions normally but when the voltage drops down it won't respond, i.e. why replacing your alternator may have worked temporarily. It created enough amperage while brand new that it essentially overrode the ground. I see this on a ton of Honda's with the battery in the trunk. Where everything works but you turn the key and lose eveything, shut it off then on and it works til you hit a certain voltage where the ground is no longer sufficient and nothing works.
