A spark plug wire puller is described which is actuated by a user squeezing a trigger biased against a handle of the tool which causes two jaw members to come together at gripping ends thereof to squeeze a wire or boot. As the user squeezes the trigger and pulls on the tool, the jaws grip the wire or boot and remove it from the spark plug. The invention is advantageous because it does not rely on a scissors action and it grips the boot in such a way so as not to damage it during the removal process.

Hand tool for gripping objects

Spark plug wire puller

A hand held electrical circuit testing for use by technicians to determine circuit conditions such as, whether a duty cycle is present or whether constant voltage is present. The invention makes use of three visual indicating means within a clear body portion of the device which reveal a lighting pattern that will provide an experienced technician with information to determine the circuit condition.

Circuit testing device

A device for testing the polarity of both a power supply and a test element such as a circuit, wire or the like. The device is comprised of a body which contains a circuit board, a probe extending from one end of the body, and two lead wires extending from the opposite end of the body. The device will work on any DC voltage supply having a voltage from 6 volts to 24 volts.
