2004 Nissan Altima battery not charging. How can I diagnose battery and alternator?
you can test the alternator with a multimeter easily. with the engine running hook the meter leads up to the battery. red to positive black to negative. with the meter set on volts dc, you should have between 13.5 and 14.5 volts. less than that, and the alternator is bad. unless you have a load tester you will have to go to autozone or somewhere and have the battery load tested.
