If I leave my car off for more then two days it dies. This has been going on for 3 months now. I drive my car even day, so it hasn't been too big of a problem. Today I jumped it and removed the positive cable and it died. That means it has to be the alternator, right?

 

your alternator is probably dead, but how i would test it is if you have a volt meter and with your car running it should read 14v if not then your alternator is gone.

 

You're battery might not be able to hold a charge anymore too, so make sure you get that tested as well.

 

thanks guys. I test the car
12.5 with car off.
14.3 with car on.

 

Don't EVER remove your battery terminal while the vehicle is running again, you can potentially damage some very expensive hardware. With places like autozone and others that offer FREE testing there is no reason for you to do that.

 

yeah go to autozone cause they can actually do a load test on it and tell you how good the alternator is and the battery as well, that's the best way to eliminate problems

 

i didn't know that. Thanks
