In this article, we will discuss the wiring diagram for a hazard 3 pin flasher relay. If you are experiencing issues with your flasher relay, this guide will provide insight into how to properly wire a 3 pin flasher relay for all types of vehicles.
What is a 3 Pin Flasher Relay?
A 3 pin flasher relay is a device that controls the turn signal and hazard lights on your vehicle. When the relay receives a signal from the turn signal switch or hazard switch, it will send power to the lights. The 3 pin flasher relay is a vital component in ensuring that your vehicle’s turn signals and hazard lights function properly.
How Does a 3 Pin Flasher Relay Work?
The 3 pin flasher relay works by receiving power from the battery and passing it on to the turn signals and hazard lights. When you engage the turn signal or hazard switch, it sends a signal to the flasher relay, which then switches power to the corresponding lights. The relay will then turn on and off in a specific pattern, which creates the blinking effect that is seen when the turn signals are engaged.
There are three pins on the 3 pin flasher relay:
- Power pin – This pin receives power from the battery.
- Load pin – This pin sends power to the turn signals and hazard lights.
- Ground pin – This pin is connected to the vehicle’s ground circuit.
How to Wire a Hazard 3 Pin Flasher Relay
Wiring a hazard 3 pin flasher relay is a relatively simple process, but it is important to follow the proper steps to ensure that it is wired correctly.
Step 1:
Disconnect the negative battery cable to prevent any electrical issues while wiring the 3 pin flasher relay.
