Hello all,

I'm trying to figure out if I have a bad alternator. For one, my battery symbol illuminated and then the electrical power started to get low then when I got home the battery completely died. I swapped out batteries from by brother's GT and the car started but I still got the battery light. I then disconnected the neg wire from the battery and the car immedietly died. Wouldn't this suggest a bad alt since the alt provies all electrical power once the car is on? Also, if you have a good alt, shouldn't you be able to disconnect the battery while the car is running and the car should continue to run right? I haven't hooked up a voltmeter yet but I have an autometer volt gauge and it reads around 12 while the car is running with my brother's battery. Any ideas?

Sounds like your alternator is shot, best bet would be to take it to your local auto part store, have them test it (it's free) to confirm. New alternators are a couple of hundred dollars.
