It could be that it's charging OK and you've got some kind of electrical load drawing the battery down when the key is off. If a charging system analysis confirms that it is not charging, then you've got to go back to the alternator and start there. Use your multimeter to BE ABSOLUTELY SURE it is putting out 13.8 volts. I seen them put out 12 volts, which will keep the charging light out but not replenish the battery. If that's ok, go over all the wiring with a fire tooth comb. Any corrosion? Any partially broken wires? Is the voltage regulator contained in the battery or is on the fender wall? Does your charging indicator come on when you turn the key to RUN without starting the engine?
What else can I help you with?

Alternator is over charging how do you fix it?
It depends on the year of the vehicle. Newer (late 60s/early 70s on) had "internal regulator alternators", so the alternator needs to be replaced. Older cars have a regulator, usually mounted on a fender well, the fire wall, or the radiator support which canb be replaced independently of the alternator.
