Have your charging system checked. Sounds like the alternator is not working.

Did you actually do any testing first?

Like Shoebox asked, have you actually tested anything, or are you just assuming the dash voltage gauge is correct? If you have a simple multitester, set the range to 25V DC and check your voltage at the battery both running and off.

If you think the alternator is bad, take it to any of the major auto parts stores, and they will hook it up to a test machine usually for free.

Guessing can get expensive...
