  • Patent number: 4282475
    Abstract: A motor vehicle battery charger is mounted on and carried with the motor vehicle. A tension releasable power source connector automatically disconnects the charger from the stationary source of alternating current power when the vehicle is driven off. A first relay is used to prevent discharge of the battery when the charger is disconnected from the power source and to prevent current flow from one battery to another where a dual battery system is used. A second relay is used to disconnect the charger when the vehicle electrical system is connected to the batteries.

The stud passes through a hole in the towbar whereby the base support portion of each ball member frictionally engages the towbar on opposite sides thereof.
