An auto diagnostic apparatus having jawed, needle-toothed clips for connection to variable output wires of engine sensors adjacent to the sensors, and a processor which converts the output voltages to output values in reader friendly units understandable to the auto technician, and which stores and continuously updates the minimum and maximum output values for diagnosing intermittent or periodically interrupted electrical current. The needle-toothed clips establish an electrical connection to the variable output sensor wire without damaging the insulation or integrity of the sensor wire.
