Default Re: What are the symptoms of a dead alternator?

get a volt meter and check your battery. If you can get it started then it should be running at around 14 (point something) volts which means its charging. If its running at 12 or less, usually around 9 if its a fully charged battery, the alternator isnt charging.


Will your radio operate when the key is turned to accessories? Then the radio shuts off the second you turn the key to operate the starter, then your battery isnt giving enough juice which would be the result of a low/dead battery or a poor connection (usually at the battery itself).

Some cars have a voltmeter in their gauge cluster and it will give you a rough estimate of the volts.

Do you have a sound system (Subwoofer) ?



Oh and after all that babbling, I'm pretty confident by reading your post that your original diagnosis is right on the money. What school do you go to?
