Electrical Components and Wiring

Switch

An electrical device used to turn the current on and off in a circuit.

Fuses

Devices that prevent circuit damage by stopping excessive current flow.

Relay

A switch turned on/off by current, where a smaller current controls a larger current.

Resistor

A component that resists current flow, reducing amperage and causing voltage drop.

Motors

Devices that use magnetic fields to create rotary movement.

Transformer

A device that changes output voltage/amperage from input voltage/amperage.

Thermistor

A type of resistor whose resistance changes with temperature, used in temperature sensors.

Soldering

The process of joining wires using a melted mixture of metals.

Wiring diagrams

Visual representations that show connections and electrical systems in a vehicle.

Circuit protection device

Devices like fuses and circuit breakers that open circuits when current flow is too high.

Blade fuses

The most common type of fuse, available in various amp ratings and sizes.

Solenoid

An electromechanical device that converts energy into mechanical linear movement.

Connector

A device that connects electrical circuits and allows for disconnection if needed.

Splice

A joining of two wires together to maintain electrical continuity.

Wiring harness

Groups of wires bundled together to organize and protect electrical wiring in a vehicle.

Cabling

A term referring to large-diameter wire used to transmit electrical signals or power.

Crimping tools

Tools used for quickly and effectively making connections with solderless terminals.

Heat shrink tubing

Used to protect and insulate wire joint connections after soldering.

Twisted pair

Two wires twisted together to reduce electromagnetic interference and improve signal integrity.

Mylar tape

A type of electrically conductive material used to wrap around wiring harnesses for shielding.
