Auto electric supplies are components necessary for the proper functioning of an automobile's electrical system. They are used to power the vehicle's lights, ignition, and other electrical components. Auto mechanical supplies include batteries, wiring, connectors, switches and relays.  

Batteries 

They provide the electrical power needed for the vehicle to start and run. They come in a variety of sizes and amperage ratings, and are typically designed for either 12-volt or 24-volt systems. Lead acid, gel cell, and AGM batteries are all commonly used in automobiles.

Wiring 

Wiring is necessary to connect the various electrical components in an automobile. It is typically made of copper or aluminum and is insulated to protect it from heat and corrosion. Wiring is available in a variety of gauges, depending on the amount of current it needs to carry.  

Connectors 

They are used to join two or more pieces of wiring together. They come in a variety of styles, such as bullet, spade, and ring terminals. They are typically rated for the amount of current that they can carry, and must be chosen carefully to ensure a proper connection.  

Switches 

They are used to control the flow of electricity in an automobile. They are available in a variety of styles, such as toggle, rocker, and push-button, and can be used to control the lights, ignition, and other electrical components.  

Relays 

They are used to control the flow of electricity in an automobile. They are typically used to control high-powered electrical components such as headlights and air conditioning.
