Alternator / Battery problem...I think

[student of life]

As I was driving home a few nights ago, I started to notice that my dashboard lights were dimming. As I turned down my street, the radio started turning on and off. As I pulled into my driveway, my engine started sputtering, and finally died. The car, of course, wouldn't start. Well I removed the battery and took it down to the local auto parts store, and had it tested. BAD BATTERY the test read. So they gave me a new battery, which I installed. I took it back to the auto parts store and had them test the alternator - which tested good.Well, the same problem occured as I was driving home again last night. Does anyone have any ideas as to what this could be? Could the alternator be overcharging and killing the battery? I'm confused and don't have the money to send a mechanic hunting. I'm just curious if anyone else has had a similar problem.

Thanks for the help!

Professional auto electrical troubleshooting is cheaper than you think and they can run down really tough problems quickly. Just be sure to get a specialist on it out of the yellow pages. Worth every penny!

A bad alternator should light up a couple warning LEDs near the gauge cluster but alts can die slowly. If you can, have them test it while you're experiencing problems.

Just A Few Months Ago I Had The Same Prob. With My 95 J30 And The Alternator Was The Problem With Mines.....I Also Had Brought A New Battery And It Died So Im Guessing That You Should Check Into Your Alt.
