Either the charging circuit is not functioning properly (e.g., the wiring and components apart from the alternator itself) or there is a phantom load in the vehicle’s electrical system that is discharging the battery even as the vehicle sits idle and is completely off. To determine which of these is the fault, and have the necessary repaired performed, the recommended service is an electrical system diagnostic. If you request that service, the responding certified mechanic will get this diagnosed and resolved, right at your location.
