ABSTRACT:
A vehicle-starting circuit with excessive voltage detection in which a battery switch assembly including a first battery switch normally connecting the starting batteries in parallel, and a second battery switch operatively connecting or disconnecting the starting batteries to the stalled vehicle battery. A first control is provided for actuating the second battery switch, and is connected to the second battery switch for connecting the starting batteries in parallel to the stalled vehicle battery. A second control is connected to the first battery switch for actuating the first battery switch to one position for series connection when the second control is "on" and for allowing the first battery switch to return to normal position for parallel connection when the second control is "off." A voltage-detector is connected to the starting batteries and to the second control for turning the second control "off" if actuated. The first control includes a first control switch connected to the stalled vehicle battery, and a first transistor assembly connected to the second battery switch for connecting the starting batteries to the stalled vehicle battery. The second control includes a second control switch connected to the stalled vehicle battery, and a second transistor assembly connected to the first battery switch for connecting the starting batteries selectively in series. The trigger includes an SCR activated in response to the reference voltage, and a third transistor assembly connected to the SCR and to the second control switch for conditioning the second control switch upon activation of the SCR to connect the starting batteries in parallel. A trickle charge circuit connects the starting batteries to the stalled vehicle battery through the outlet for supplying a limited current.
