IDENTIFICATION COLOUR: Describes a colour scheme for electrical wiring.
INSULATION: Describes any material which does not conduct electricity. It is used to prevent the flow or leakage of an electrical conductor.
INSULATE: Describes the practice of covering an item with a non-conducting material to prevent the transmission of heat and electricity.
INSULATING CAP: Describes the insulated top of a coil tower
INSULATING TAPE: Describes the tape (usually black PVC) use to wrap around electrical connections
LOOM TAPE: Describes a type of non-adhesive tape used as a harness wrap.
LOW TENSION LEADS: Describes the wiring in an ignition system that operates as a separate entity from the high-tension wiring system. Low tension leads, capable of carrying only 6 or 12 volts, include the battery cables, some of the coil connections), the ignition switch wiring and the non-high-tension wires going to the distributor.
MAGNETO: Describes an electrical device that generates electrical current when rotated through an external power source, producing either low- or high-tension current.
OPEN CIRCUIT: Describes an electrical system in which a wire is either broken or disconnected, leaving the system ineffective.
OPEN-LOOP: Describes an operating condition based on programmed instructions that are not modified by a feedback system.
PARALLEL: Describes two or more electrical components connected in parallel that each receives identical voltage resistors.
PARALLEL CIRCUIT: Describes an electrical circuit with two or more resistance units wired in such a way to as allow current to flow through both units at the same time. In a parallel circuit, current can flow independently through several components at the same time.
POSITIVE CONNECTIONS: Describes the connections found in an electric circuit through which electricity flows constantly.
RELAY: Describes a switch that is electro-magnetically used to make and break the flow of current in a circuit.
ROUTE: Describes the single direction that wiring plans must take.
SCHEMATIC: Describes a drawing system using standardised symbols that displays the components and wires in a vehicle electrical system.
SHORT CIRCUIT: Describes a situation in a car electrical system where a positive wire touches the ground instead of going through the prescribed component. Described as a "short circuit", this will usually cause a fuse to burn out.
SINGLE-CONNECTOR SYSTEM: Describes an electrical circuit, where only a single wire leads from the voltage source to the load, with the car body completing the circuit.
SIMPLE CIRCUIT: Describes the start level circuit plan that includes an electrical power source, a load, and the minimum of wire to connect them.
SPADE TERMINAL: Describes a terminal form with two forked ends, either straight or with upturned tips used to connect a wire to a screw or stud terminal. It is more convenient to install than ring term, but slightly less secure for rugged applications; spade terminals come in soldered and unsoldered versions.
SPLIT LOOM: Describes a flexible conduit used to bundle wires into a harness.
STRAND: Describes one of the component wires twisted together to form an electrical conductor.
TERMINAL: Describes the connecting point in an electric circuit.
TERMINAL BLOCK: Describes an assembly featuring two rows of terminals screws that are used to connect the circuits in several wiring harnesses
WIRING DIAGRAM: Describes an accurate diagram that details the various electrical units and the wiring arrangement necessary for a vehicle electrical system to function efficiently.
WIRING HARNESS: Describes the collection of colour-coded wires connected to all of a vehicle's electrical components.
