Hello, first I would check the battery state of charge and the ability to sustain a load. It is possible that the battery is the root of the concern. Once you know you have a known good battery, then check the charging system. It is indeed true that the charging system may not be working properly to maintain battery voltage. Battery voltage is what sustains all the accessories and components of the vehicle. If battery voltage is not something that can be maintained, other electrical components fail.
