Understanding 5 Pin Relays and Wiring Diagrams

Before we dive into the testing process, let’s take a moment to understand the basics of 5 pin relays and how they are connected using wiring diagrams. Having this fundamental knowledge will help you navigate through the testing process with confidence.

5 pin relays are commonly used in automotive and industrial applications to control electrical circuits. They consist of five pins or terminals, each serving a specific function. Understanding the purpose and function of these pins is crucial for proper relay testing.

Wiring diagrams, on the other hand, provide a visual representation of how the different components in a circuit are connected. They show the interconnections between relays, switches, wires, and other electrical components. By referring to a wiring diagram, you can determine the correct terminal connections for a 5 pin relay.

Let’s take a closer look at the pins in a typical 5 pin relay and how they relate to the wiring diagram:

Pin Number Function
Pin 30 Main power supply input
Pin 87 Main power output
Pin 86 Coil power input (positive)
Pin 85 Coil power input (negative/ground)
Pin 87a Additional power output (only present in certain relay designs)
