This evening after driving my car for about ten mins, it just powered off (lights, radio, windows, locks)and would not come back on. The battery is less than a month old. I'm thinking its the alternator...any other ideas? I just paid a lot of money for a tune up and really don't have a lot of money left to pour down the drain...please help!

 

I guess you have a Chrysler, what model, engine size, year?

Will it crank? Can you take a voltage reading across your battery posts? Are the battery cables clean, on both ends? Any codes?
