Alternator power source

Claim 1

A vehicle operated power source in combination with an accelerator equipped internal combustion engine driving an alternator and having its power output and field winding connected with the vehicle battery by wiring, the improvement comprising: a gate controlled rectifier connected in series in the alternator to battery wiring; a relay having a coil and having one end of its coil grounded, said relay having a magnetic switch normally connecting the alternator output potential to the gate of said controlled rectifier to render the latter conductive; a normally open circuit connected in series with said alternator power output, said circuit including a pair of power output terminals, one said power output terminal being connected with said alternator power output; current sensing means connected with the other power output terminal and connecting the other end of the coil of said relay with said battery for energizing said relay when said normally open circuit is closed; a solenoid having one end of its coil grounded; electronic switch means connecting the other end of the coil of said solenoid with said battery and said current sensing means, said solenoid being energized when said normally open circuit is closed and being operatively connected with said accelerator for moving said accelerator in an engine accelerating direction; and, means bridging said power output terminals for energizing said relay and said solenoid.
