The past 2 weeks my battery has been draining out on me. Drive it during the day and by next morning it's completely dead. I put it on the charger, 2 amp trickle, next morning it starts, I drive it, no problems. Next morning, dead. The battery was new, 2 months old. Can the alternator drain it while the car is off. I have a multi-meter, but I'm a bit electrically challenged. What would be the best way to test it without taking it out? Thanks for any suggs.
