Can you give us the actual voltage reading for the charging system? Using a digital multimeter across battery posts, the generic spec for a full charge is around 12.6 volts. With the vehicle running, I take a second reading across battery posts, the second reading should be higher than the first, if the charging system is working. With vehicle idling in drive, have a helper with foot on the brake, all accessories turned on, I like to see charging system voltage as much over 13 volts as I can get.
