ABSTRACT:
An automatic engine control system in which all solid state circuitry is isolated by open switches, open relay contacts and reversed biased diodes from either ground or the power supply during the standby state of the system. All solid state circuitry except that contained in the alarm circuitry is isolated during an alarm condition after shutdown of the engine has been effected. Novel circuitry is used for allowing the latching of a fault response relay while at the same time removing ground from other solid state circuitry. Further, the automatic engine starter and controller of the present invention utilizes unique and novel means for controlling the battery charger of the controlled engine and for initiating and resetting solid state timing circuitry.
