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.
