Find Your Harley Davidson Starter Relay Location Easily! (2024)

As a Harley Davidson owner, you may already know how important the starter relay is in powering your bike’s ignition system and initiating the starting process. However, when the starter relay malfunctions, it can create significant issues and ultimately lead to a frustrating experience.

One of the most challenging aspects of dealing with a faulty starter relay is locating it, especially if you are not familiar with the different Harley Davidson models and their respective starter relay locations. In this article, we will guide you through the process of finding the starter relay location in your Harley Davidson motorcycle, to ensure you can troubleshoot any issues effectively.

What is a Starter Relay and Its Function in a Harley Davidson?

A starter relay is an essential component of the ignition system in a Harley Davidson motorcycle. It is responsible for initiating the starting process by transmitting electrical power from the battery to the starter motor. The starter motor, in turn, cranks the engine until it starts running on its own.

The starter relay functions as a switch that controls the flow of electrical current to the starter motor. When the ignition key is turned on, a low voltage signal is sent to the starter relay, which activates the relay switch. The switch then connects the battery to the starter motor, allowing it to turn the engine over. Once the engine starts running, the starter relay disengages, and the starter motor stops cranking.

Without the starter relay, the engine cannot start, and the motorcycle is rendered useless. Therefore, it is essential for Harley Davidson owners to understand the function of the starter relay and its location on their particular bike model.

Understanding the Starter Relay Location on Harley Davidson Models

Knowing the location of your Harley Davidson’s starter relay is essential for troubleshooting and identifying any starting issues you may encounter. The starter relay is responsible for initiating the starter motor’s operation and is a crucial component in the ignition system. The starter relay is commonly located in the same area, but it can vary based on the model and year of your motorcycle.

Here’s a general guide on how to locate the starter relay on various Harley Davidson models:

However, note that specific models and years may have different variations in the starter relay’s location. It’s best to refer to your owner’s manual or consult with a Harley Davidson technician if you’re unsure.

Locating the Starter Relay in Older Harley Davidson Models

For older Harley Davidson models, locating the starter relay may require additional effort and attention. Typically, older models have the starter relay located near the battery or under the gas tank.

If you’re having trouble finding the starter relay on an older model, try searching for a small rectangular or square box with wires attached to it. This box is typically mounted on the frame or a nearby bracket and can be difficult to spot due to the surrounding components.

Finding the Starter Relay on Newer Harley Davidson Models

Newer Harley Davidson models have undergone design changes, affecting the starter relay’s location. The starter relay is now commonly found inside the electrical caddy or behind the left side cover of the motorcycle.

To locate the starter relay on newer models, begin by removing the left side cover or consulting the owner’s manual. Look for a small rectangular or square box with wires attached to it. This box is commonly secured to the frame or a nearby bracket.

Steps to Identify and Verify the Starter Relay Location

If you’re still having trouble locating the starter relay, follow these steps:

1. Refer to your owner’s manual for specific information.
2. Identify and locate the battery box and other primary electrical components.
