Ok, if the alt. is bad, you will get a reading of less than 12.8 Volts or more than 15 volts. If your reading is high, the alt is overcharging. If you are reading less than 12.8 volts, your alt. is not charging. Check your alt fuse, belt tension and connections at the back of the alt. first. Then you can remove both your alt and battery and haul them up to Advance Auto or AutoZone, etc to have them checked for free. Eliminates a lot of the unnecessary guessing. A bad alternator can often 'kill' a battery also.

If your only ride is your DSM, have someone jump you for a while. IE, with the other car running, keep charging your battery for at least 1/2 hour. Or, if available....use a battery charger. That should give you enough juice to make it before it dies. No radio, fan and lights if possible. They are just draining your battery even faster.
