Abstract

An accessory circuit arrangement for an internal combustion engine employing a D.C. battery source for the starter and ignition circuits which permits the alternate utilization of the same external A.C. source as a battery charger and an ignition booster.

Claims

1. In combination with starter and ignition circuits including a battery and a starter motor, the improvement comprising;

circuit means for supplying rectified A. C. current selectively to said battery or said ignition circuit including means operative as a function of the energization of said starter circuit for ceasing supply of said A. C. current to said battery and for supplying rectified A. C. current to said ingition circuit and connector means adapted for connection to an external A. C. source.

2. In combination with starter and ignition circuits including a battery and a starter motor, the improvement comprising;

circuit means for selectively supplying rectified A.C. current to said battery and said ignition circuit;

said circuit means including connector means adapted for connection to an external A.C. source; and

said circuit means including parallel branch circuits respectively interconnecting said connector means with said battery and said ignition circuit.

3. The combination of claim 2 including relay switching means for controlling the selective supply of rectified A.C. current to said battery and said ignition circuit.

4. The combination of claim 3 wherein said starter motor circuit includes a normally open solenoid operated switch, said ignition circuit including a manually operated ignition switch for selectively supplying battery power to said ignition circuit and the coil of said solenoid operated switch;

and said circuit means including a third branch circuit for energizing said relay switching means concomitantly with the energization of the coil of said solenoid operated switch.

5. An accessory circuit arrangement for the selective supply of rectified A.C. current to a battery and an ignition circuit, comprising;

a plurality of connector terminals adapted for connection to a battery, an ignition circuit, and ground;

a connector adapted to be plugged into an A.C. source;

parallel branch circuits interconnecting said connector with at least two of said terminals;

switch means for making and breaking said parallel branch circuits;

means in circuit with at least one other of said terminals for actuating said switch means; and

means associated with said branch circuits for supplying rectified A.C. current to said at least two terminals for the selective supply of the same to a battery and an ignition circuit.
