In this FAQ-style guide, we’ll walk you through the ins and outs of testing your Harley’s ignition module like a seasoned mechanic. Buckle up, rev your engines, and let’s dive into the world of spark, fire, and motorcycles!
How Do You Test a Harley Ignition Module
Testing a Harley ignition module isn’t rocket science, but it does require some know-how. Here’s a step-by-step breakdown to help you get in tune with your bike’s ignition:
1. Prepare for the Test
Before you get started, make sure you have all the necessary tools and gear in your garage. You’ll need a multimeter, a fresh cup of coffee (or your preferred beverage), and your trusty Harley repair manual. Safety first, always!
2. Locate the Ignition Module
Time to get intimate with your bike! Locate the ignition module on your Harley. It’s usually nestled somewhere near the battery or the frame. Reach out and give it a gentle pat—it’s about to reveal its secrets to you.
3. Check for Power
This step is where the magic happens. Grab your multimeter and set it to the “Volts” mode. Connect the red lead to the positive terminal and the black lead to the negative terminal of the ignition module. Now, turn on your ignition and voilà—your multimeter should display a voltage reading, ideally between 12 to 14 volts. If the reading gives you the cold shoulder, you might need to say goodbye to your ignition module.
4. Test the Trigger Wire
No, we’re not talking about setting off explosions here. Grab your multimeter once again and switch it to the “Ohms” mode. Now, disconnect the trigger wire from the ignition module and touch the multimeter leads to the terminals. A healthy ignition module should show a resistance reading within the manufacturer’s specifications. If it’s throwing tantrums, it might be time for a replacement.
5. Say Cheese… or Spark!
To truly put your ignition module to the test, you need to check if it’s generating sparks—without setting things on fire, of course. Carefully remove the spark plug wire and attach a spare spark plug to it. Ground the spark plug’s base to the engine (using a rubber-handled tool for safety) and crank the engine. If you see a spark, congratulations, you’ve got ignition! If not, it might be time to give the ignition module a swift kick out of your bike.
What Causes a CDI Box to Go Bad
Ah, the enigmatic CDI (Capacitive Discharge Ignition) box—the brain behind your Harley’s ignition system. But what can send this mysterious component into an early retirement? Here are a few possible culprits:
