When it comes to understanding the wiring configuration of your vehicle, it’s important to know the ins and outs of every component. That’s why we’re here to provide you with the ultimate guide to the 7 pin flasher relay wiring diagram. Whether you’re a car enthusiast or just looking for some helpful tips and information, this article is for you.
What is a 7 Pin Flasher Relay?
A 7 pin flasher relay is an electronic device that controls the turn signals and hazard lights of a vehicle. It works by sending an electric signal to the bulbs, causing them to flash on and off in a specific pattern. The 7 pin flasher relay is a type of thermal flasher, which means it uses an internal heating element to regulate the speed of the flashing.
How Does a 7 Pin Flasher Relay Work?
The 7 pin flasher relay works by receiving power from the vehicle’s battery. When activated, it sends an electric signal to the turn signal bulbs, causing them to flash on and off. The speed of the flashing is determined by the internal heating element, which regulates the current flowing through the relay.
The 7 pin flasher relay also contains a built-in fuse, which protects the circuit from overload and potential damage. In some vehicles, the flasher relay may be located in the fuse box or under the dashboard.
What are the Components of a 7 Pin Flasher Relay?
The 7 pin flasher relay consists of several important components, including:
- Power input terminals: These are the connections that receive power from the vehicle’s battery.
- Output terminals: These are the connections that send the electric signal to the turn signal bulbs.
- Heating element: This is the internal component that regulates the speed of the flashing.
- Resistor: This component helps to regulate the current flowing through the relay.
- Capacitor: This component helps to smooth out any fluctuations in the current.
- Diode: This component controls the direction of the current flowing through the relay.
- Fuse: This component protects the circuit from overload and potential damage.
