Abstract: A strobe light power source includes a capacitor which is alternately charged through an inverter transformer and a rectifier and discharged through a strobe lamp. A MOSFET switch is connected in series with the transformer primary and has applied to its gate electrode a rectangular wave output signal from an oscillator. The oscillator and the transformer primary are coupled to a power supply independently of each other. A breakdown diode is connected in parallel with the MOSFET to limit the voltage thereacross.

Abstract: A microprocessor controlled digital engine analyzer receives analog input signals from an engine being analyzed, engine parameter data entered via a keyboard, and function data, selecting one of several operating modes for the analyzer and which information is to be displayed, entered via the keyboard, and displays on a CRT screen the selected information such as cylinder firing order, RPM, Dwell, KV and DC volts, alphanumerically, information such as primary and secondary ignition and voltage, alternator and fuel injector information through the use of continuous waveform patterns, and additional information pertaining to Dwell, KV and Cylinder Shorting through the use of bar graphs.
