Abstract: The present invention allows a technician a quick reference diagnostics of an automotive individual electrical circuit by replacement of the OEM relay with a diagnostics relay incorporating a series of LED bulbs designed to illuminate individually upon completion of each internal switching function. Adjacent to an LED is a voltage portal which allows measurement of voltage during each function stage of relay switching.

Abstract: An automotive circuit tester consisting of a jumper wire having a spring loaded clip at one side and voltage probe at the other incorporates a fuse holder utilized for the housing of an electric current resectable fuse.

Abstract: The present invention relates to a quick reference electrical voltage testing tool utilizing a variable voltage range light bulb and digital read out voltage meter both incorporated in the testing tool's handle. The variable voltage range light bulb indicates to the user the knowledge of voltage present and the digital voltage read out indicates the measured amount of voltage available to the tested component. This allows for a faster diagnosis of an electrical problem particularly when voltage sensitive components are being tested. When testing electrical components for non-operation, this quick reference tool will allow a much quicker diagnoses of an electrical problem without the need of a voltage meter.
