does the battery light in dash work? there are 2 fuses for the alternator. one will be a lorge fuse, usually 60-100 amps then another 10-15 and small fuse. can also take it to local auto parts stores, most will see if charging system is working for free. are you sure its not just a bad battery cable or bad connection on block or fuse block? is it completly dead or do dash light still come on when you turn the key?
