A 3-pin flasher relay is an electronic device used in automobiles to control the turn signal and hazard warning lights. It is a small, plastic box that connects to the wiring harness of a vehicle’s electrical system. The three pins are used to control the power supply, ground, and output of the flasher. In this article, we will provide a comprehensive guide on the wiring diagram of a 3-pin flasher relay, including its manual and various FAQs.
Three Pin Flasher Relay Wiring Diagram
The following table shows the wiring diagram of a 3-pin flasher relay:
| Pin Number | Wire Color | Description |
|---|---|---|
| 1 | Yellow | Power Supply |
| 2 | Black | Ground |
| 3 | Green or Red | Output |
The flasher relay is usually labeled with numbers or letters corresponding to the pins.
Pin 1: Power Supply
The power supply pin is connected to the battery of the vehicle. It supplies voltage to the flasher relay, enabling it to function. The wire color used in this pin is usually yellow.
Pin 2: Ground
The ground pin is connected to the chassis of the vehicle. It is used to complete the circuit when the flasher is activated. The wire color used in this pin is usually black.
Pin 3: Output
The output pin is connected to the turn signal and hazard warning lights of the vehicle. It controls the flashing of the lights when the flasher is activated. The wire color used in this pin is usually green or red.
3 Pin Flasher Relay Wiring Diagram Manual
The 3-pin flasher relay wiring diagram manual is a guide that provides step-by-step instructions on how to wire a 3-pin flasher relay. It includes diagrams and illustrations that make it easy for anyone to understand the process. Here is a step-by-step guide on how to use the manual:
Step 1: Identify the Wires
The first step is to identify the wires in the vehicle’s electrical system. You need to know which wire is the power supply, which is the ground, and which one controls the turn signals and hazard warning lights. Once you have identified the wires, you can proceed to the next step.
Step 2: Connect the Wires
The next step is to connect the wires to the flasher relay. The power supply wire should be connected to pin 1, the ground wire to pin 2, and the output wire to pin 3. You need to make sure that the connections are secure and tight.
Step 3: Test the Flasher Relay
Once you have connected the wires, you need to test the flasher relay to make sure it is working properly. You can do this by turning on the hazard warning lights and the turn signals. If the lights are flashing at the correct rate, then the flasher relay is working properly.
Step 4: Secure the Connections
After testing the flasher relay, you need to secure the connections by using electrical tape or cable ties. This will prevent the wires from coming loose and causing any electrical shorts or other issues.
FAQs
What is a flasher relay?
A flasher relay is an electronic device that controls the flashing of turn signals and hazard warning lights in a vehicle.
What are the types of flasher relays?
The two types of flasher relays are thermal and electronic. Thermal flasher relays use a bi-metallic strip to control the flashing, while electronic flasher relays use an integrated circuit.
What causes a flasher relay to fail?
A flasher relay can fail due to various reasons, such as a blown fuse, a broken wire, or a faulty relay. It can also fail due to excessive heat or moisture.
How do I replace a flasher relay?
To replace a flasher relay, you need to locate it in your vehicle and disconnect it from the wiring harness. Then, you need to connect the new flasher relay to the wiring harness and test it to make sure it is working properly.
Can I install a flasher relay myself?
Yes, you can install a flasher relay yourself if you have some basic knowledge of electrical wiring. However, if you are not confident in your abilities, it is recommended to seek the help of a professional.
