If you have voltage meter you can atleast see if the alternator is working. Start the car and connect the voltage meter to the battery cables. You should get a reading of anywhere from 13-14 volts even with high beams on if the alternator is working.
When mine was going i was getting a reading of 12 - 12.5 which is not enough to power the car and recharge the battery. I ended up getting a new/used alternator but it may have been my voltage regulator which is part of the alternator.
