The 12-volt cigarette lighter receptacle is a common feature in modern vehicles. It was initially designed as a place to plug in cigarette lighters, but now serves as a convenient way to power a variety of electrical devices. Whether you want to charge your phone or power your GPS, the 12-volt cigarette lighter receptacle is an essential part of vehicle electronics. In this article, we will explore the wire diagram for the 12-volt cigarette lighter receptacle.
What Is a 12-Volt Cigarette Lighter Receptacle?
A 12-volt cigarette lighter receptacle is an electrical outlet that was designed to supply power to cigarette lighters. It has a cylindrical shape and is located in the dashboard of a vehicle, usually near the radio or climate controls. The 12-volt cigarette lighter receptacle has a positive and negative electrical terminal, which is used to connect to an electrical device requiring 12 volts of power.
Over time, the use of cigarette lighters has declined, but the receptacle remains. The 12-volt cigarette lighter receptacle can now be used to charge various devices such as cellphones, tablets, GPS navigation devices, and even portable refrigerators.
The Wire Diagram of a 12-Volt Cigarette Lighter Receptacle
The 12-volt cigarette lighter receptacle wire diagram shows how the power flows from the battery, through the fuse, and into the receptacle. The diagram is relatively simple, and understanding it can be helpful when diagnosing problems or installing new accessories.
The Positive Wire
The positive wire of the 12-volt cigarette lighter receptacle is usually red or orange. It is connected directly to the positive terminal of the vehicle battery. The wire also passes through a fuse to protect the electrical system from electrical shorts or overloads. The fuse is typically rated between 10 and 20 amps, depending on the vehicle’s electrical requirements.
The Negative Wire
The negative wire is usually black and is connected directly to the negative terminal of the vehicle battery. This wire provides a return path for the electrical current that flows through the 12-volt cigarette lighter receptacle. It is important to ensure that the negative wire is securely connected, as any loose connections can cause electrical problems and even a fire.
The Cigarette Lighter Socket Wire
The cigarette lighter socket wire connects the receptacle to the cigarette lighter socket. It is usually connected to the back of the receptacle using a metal clip. The wire is often black and can be traced back to the center of the receptacle, where the cigarette lighter is inserted.
