You may want to remove and clean all of the cables that are involved with this and make sure that there is no shorts is the wiring and also check the belt and make sure that it is tight and see if there is a master fuse for the charging system under the hood also check to see if the solinoid is working properly you can also take it to a autozone and they can do a free diagnostics of the system

If you have a fuse it will be in the power distribution center near the battery main fuses and relays are inside.
Check the charging system with a volt meter right at the battery. Battery standing charge should be no lower than 12v if charging you should read between 13 and 14 volts running, about 13 with all electricals turned on. If not, the alternator isn't working OR the regulator has failed. (some regulators are part of the main computer but you need to check which system you have. AND do check for fuses.
If charging system is working you may have a system draw that is pulling the system down overnight. Check that with an ammeter between either cable (removed from battery) and battery connection...pull fuses one by one till draw disappears then check components in that system. Don't be concerned with "low Draw" items such as radio that always pulls something to keep memory and clock working.
