Abstract
An improved circuit supplies electrical power to a vehicle accessory load, such as a load that is powered through a vehicle accessory load connector or cigarette lighter plug. The circuit utilizes battery voltage comparator and timer switching circuitry to interrupt the supply of power to the accessory load if the engine-driven alternator fails to charge the storage battery for at least a predefined time interval (i.e., when the vehicle engine is not running), and to automatically re-establish electrical power supply to the load when battery charging resumes (i.e., when engine operation resumes).
