Abstract

The adapter includes a housing containing a rectifier for supplying flash voltages to an LED. The rectifier rectifies inductive signals derived from an inductive pickup. The adapter can be used to enable a spark-ignited engine calibrator to calibrate a diesel-engine-timing meter by converting the inductive electrical signals from the calibrator to light signals for the diesel timing meter. The adapter also can be used to enable a diesel-engine-timing meter and analyze and time a spark-ignited engine by converting the inductive pulses derived from a spark plug wire into light impulses for the diesel-engine-timing meter.
