Electrical Charging problem 850 1997

My 850 is normally aspirated, has about 83,000 miles. My battery is less than 2 years old. It just got really cold a couple of days ago. I have been keeping my car outside. The other morning, it wouldn't start (after being in the garage all night). Had lights & radio, though. Hooked up cables to my wife's car, and immediately the fuel pump kicked in. Without starting the booster vehicle, I tried starting the 850, and it did no problem. I immediately drove over to AutoZone to get my free replacement (<2 years, no pro-rated stuff), and they tested it. The battery had plenty of charge, however, my alternator was only registering a little over 10V. After I started it, it took a good 15 seconds for the alternator to rise to about 13.5V. According to the sales guy, it should have jumped up much quicker. He thinks there may be a short, or something that draws a current while the car is off, and is enough to prevent the car from starting. Also, my trunk latch hasn't worked in about a month. Since the locks are power, I wonder if my trunk problem is related. Any advice?

If your trunk latch isnt working then your trunk light maybe on. There is a switch to turn it off. You are probably draining your battery... Mike

Mike - that's a good suggestion, only if my trunk had a light. I wish it did, instead of heated side view mirrors or the headlamp wipers. Talk about oversight, sheesh. Thanks for the input though.

He can check to see if the light is staying on by folding sown one of the rear seat backs to see if the light is still on.
