Use a digital multimeter across the battery posts, take a reading, everything turned off. The generic spec for a full charge is around 12.6 volts. If the battery is down, take it off and get it charged. You can't do any testing if the battery is down.
Replacing parts may not fix it, could be a wiring issue somewhere? Forget the jumper cables at the moment, check that the battery has a full charge, first.
Don't use the alternator to charge a dead battery. Just my opinion.
