Fish hook

A portable hand held diagnostic tool which non-invasively detects an electric field when placed adjacent a component of a spark plug firing portion of an ignition system and provides a positive indication of the detected electric field. A printed circuit board containing a control circuit, a replaceable battery supply, an ON/OFF switch, an indicator such as an LED, and a pickup antenna, is slidably mounted within the hollow interior of a dielectric tubular case. The antenna is located adjacent a pickup end of the case and detects the electric field generated by an ignition system during firing of a spark plug which actuates the LED in response to the detected firing. The dielectric case is free of external metal parts adjacent the pickup end to help minimize arcing. A battery test circuit may be incorporated into the control circuitry to ensure an adequate power supply for operation of the control circuitry. A fixed or variable resistor enables the sensitivity of the firing pickup to be selected.

Spark plug gapper

A battery post and terminal cleaner includes a hollow base with a hollow mandrel in the base with a space around the mandrel. A scraper element is disposed in the space between the mandrel and the outer surface of the base. The outer portion of the base houses the scraper blade. A reamer extends from and above the base and a cap is provided removably connected to the base and covers the reamer. The cap has a ribbed surface to provide a friction surface which is engaged by the hand for operating the scraper. The base is ribbed and provides a friction surface for the hand when the cap is removed, for performing a reaming operation.
