ABSTRACT:
A combination shut-down trigger and annunciator may be advantageously powered by a photoelectric power supply. The shut down trigger and annunciator can include a fault detection unit responsive to a plurality of fault condition sensor inputs. A fault condition identification storage element is connected to the fault detection unit and a display is connected to the fault condition identification storage element. The photoelectric power supply is then connected to the fault condition identification storage element. The photoelectric power supply may be provided with a battery backup system for use when there is insufficient light incident on a photo cell to power system. The battery backup may be a rechargeable battery in the power supply can include a battery charger. The configuration of the power supply, including the photocell battery charger and backup battery allows the system to operate without drawing power from an engine CD ignition power supply.
