Harley Davidson Ignition Module Location

harley davidson ignition module location

It’s crucial to know all about your bike, especially the Harley Davidson ignition module location. For decades, Harley Davidson Motorcycles have been the embodiment of American nostalgia and liberty. From classic Panheads to modern Softails, each individual bike holds its own maintenance requirements and is unique in its own right.

It’s imperative to ensure that your Harley Davidson is maintained properly, and one key element of this upkeep is proper installation of the ignition module. In this article, we’ll explain what an ignition module does and the correct Harley Davidson ignition module location for a variety of models. Furthermore, we will demonstrate how to relocate it if you believe it has already been moved.

What Is An Ignition Module?

Responding to the engine’s combustion cycle with spark, the ignition module is a vital electronic device that enables your vehicle to run. This system has been aptly named an ‘ignition system’ and without it, you wouldn’t be able to drive anywhere.

Ignition modules can be incredibly beneficial when it comes to a more efficient combustion process and superior power output. Depending on the kind of ignition module, its purpose may vary, however they all share one primary goal: increasing engine performance by combusting fuel in an internal combustion system.

Where Is The Harley Davidson Ignition Module Location On Different Models?

As manufacturers occasionally make modifications or replace these components with newer models, the exact Harley Davidson ignition module location can vary from model to model. To illustrate this point, here are some examples:

2005 HD 883

Before replacing any parts, you may have to consider photographic evidence as there could be variations in individual bikes. As per the service manual, this particular model’s ignition module should rest above the oil tank yet discrepancies are still likely.

Heritage Springer 1998 Evo

This model features two rivets that secure the round cam cover, so if you find two screws instead, it is likely an aftermarket ignition system has been installed inside of the cam cone area. To confirm its existence and begin extracting these rivets as needed, first inspect its interior.

All Other Models

Generally, modules from other models are located in the nosecones on their right sides. These components must be attached to cam chest covers and wires should run through these covers before exiting at the rear end of each model, while 6-pin plugs should remain beneath crank pulleys for easy removal or replacement access points.

How To Properly Relocate A Harley Davidson Ignition Module Location

In some instances, you might have to switch or substitute your Harley’s current ignition module when signs such as dim headlights, trouble starting up the bike – and other related issues with faulty modules or improper positioning/connection occur. If this comes down to a required task then simply adhere to these steps:

  1. Before doing anything else, ensure that all wires are disconnected on both ends. Focus particularly on the back of the cam cover and near where your crank pulley is located. Memorize any pin configurations related to each wire throughout this process; you will need them for reconnection when finished.
  2. Start by removing your current module, which you can do either by unscrewing it, unclipping it (if possible), or cutting off its wiring (as a last resort). Then attach your new one – making sure all lines up properly beforehand – with bolts to its designated mount if necessary. Alternatively, clip/press fit the new module into place while taking extra care not to damage any of the delicate components inside.
  3. Finally, fit back the wires which have been detached into their initial positions and configurations; make sure you double check everything aligns perfectly before performing any tests or confirming a successful installation (especially when cutting through wiring etc…).
  4. To confirm your results, use a dependable tester such as OBD’s. This display will provide you with crucial information regarding electrical shorts and misfires, among other issues that may be present. By using this diagnostic process, you can accurately identify faulty modules in the system – and once done? Congratulations. You just fixed it.

Final Views On The Harley Davidson Ignition Module Location

Installing an ignition module precisely is essential for achieving the best performance from your motorcycle engine. Make sure that you adhere to its designated spot, depending on what make and model of bike you have. To ensure accuracy, consult official documents or review photo/video evidence about suitable settings for various models. Failing to do so can cause a drop in power output and efficiency as well as physical damage.
