# 3 Wire Flasher Wiring Diagram: A Step-by-Step Guide

A flasher is a simple electrical device that is used to turn a light on and off in a repetitive fashion. Flashers are commonly used in automotive applications to signal turn signals, hazard lights, and brake lights. However, they can also be used in other applications, such as to create flashing lights for stage performances or to indicate an emergency situation. This article will provide a step-by-step guide on how to wire a 3-wire flasher. We will cover the following topics: * The different types of flashers * The parts of a flasher * How to wire a 3-wire flasher ## The Different Types of Flashers There are two main types of flashers: mechanical and electronic. Mechanical flashers use a small motor to rotate a cam, which in turn opens and closes a switch to turn the light on and off. Electronic flashers use a circuit board to generate a square wave signal, which is used to turn the light on and off. Mechanical flashers are generally less expensive than electronic flashers, but they are also less reliable. Electronic flashers are more expensive, but they are also more reliable and offer more features, such as variable flash rates and flash patterns. ## The Parts of a Flasher All flashers have the following basic components: * A power input * A load (the light bulb) * A switch * A timing mechanism The power input is where the flasher receives power from the battery. The load is the light bulb that the flasher will turn on and off. The switch is used to turn the flasher on and off. The timing mechanism is used to control the flash rate. ## How to Wire a 3-Wire Flasher Wiring a 3-wire flasher is a relatively simple task. The following steps will walk you through the process: 1. Connect the power input to the battery. 2. Connect the load (the light bulb) to the flasher. 3. Connect the switch to the flasher. 4. Connect the timing mechanism to the flasher. Once the flasher is wired, you can test it by turning it on and off. The light bulb should flash on and off in a repetitive fashion. Here is a more detailed look at the wiring process: 1. Connect the power input to the battery. The power input is typically a red wire. Connect it to the positive terminal of the battery. 2. Connect the load (the light bulb) to the flasher. The load is typically a black wire. Connect it to the negative terminal of the flasher. 3. Connect the switch to the flasher. The switch is typically a blue wire. Connect it to the "S" terminal of the flasher. 4. Connect the timing mechanism to the flasher. The timing mechanism is typically a green wire. Connect it to the "T" terminal of the flasher. Once the flasher is wired, you can test it by turning it on and off. The light bulb should flash on and off in a repetitive fashion. ## Conclusion Wiring a 3-wire flasher is a relatively simple task. By following the steps in this article, you can easily wire a flasher to turn a light on and off in a repetitive fashion.
