Understanding Ignition Coil Problems in Harley Davidson Motorcycles

As a dedicated rider, encountering issues with your Harley Davidson can be frustrating, especially when it comes to the ignition system. The ignition coil plays a crucial role in your motorcycle’s engine performance, so identifying problems early can save you time and money down the road. Whether you’re experiencing hard starting, sputtering, or complete failure to start, you may be dealing with ignition coil issues. Here’s how to diagnose and tackle these challenges head-on.

Symptoms of Ignition Coil Problems

  • Difficulty Starting: If your bike is hard to start, it could be a sign of a faulty ignition coil.
  • Engine Misfiring: A misfiring engine can result from a poorly functioning ignition coil. This may cause a rough ride.
  • Reduced Performance: Noticeable drops in power can indicate issues with the coil.
  • Check Engine Light: If this comes on, it’s wise to check the ignition coil among other components.

Diagnosing Ignition Coil Issues

  1. Visual Inspection: Begin by checking the ignition coil for any visible signs of damage, such as cracks or corrosion.
  2. Testing with a Multimeter: You can use a multimeter to measure the resistance of the coil.
    • Primary Resistance: Check the primary terminals to ensure they fall within the proper range described in your service manual.
    • Secondary Resistance: Measure the secondary terminals for any inconsistencies.
  3. Swap Coils: If you have access to a similar functioning coil, swapping it may help identify whether the coil is the issue.

Replacing the Ignition Coil

If you’ve determined that the ignition coil is faulty, replacing it is straightforward. Here are the steps:

  • Tools You’ll Need: Socket set, screwdrivers, and possibly a torque wrench depending on your model.
  • Disconnect Battery: Always disconnect the battery to avoid any electrical shock.
  • Remove the Old Coil: Follow the manual to unscrew and remove the coil from its mount.
  • Install New Coil: Mount the new ignition coil in the same position, connect it properly, and reassemble any components you had to take off.
  • Reconnect Battery: Finally, reconnect the battery and test the ignition.

Additional Tips

  • Regular Maintenance: Regularly check and maintain your ignition components to prevent future issues.
  • Keep it Clean: Ensure that your bike’s electrical connections are clean and free from corrosion for optimal performance.
  • Consult Forums and Experienced Riders: Engaging with online communities can provide insights and personal anecdotes that can guide you in your repairs.

I’ve been having issues with my ignition coil too. It started misfiring and I’d lose power on the highway. Definitely a scary situation!

3

I can relate! I noticed my Harley struggling to start after my last ride. It feels like the ignition coil might be failing.

Sounds frustrating, mayocynthia! Misfires can be so annoying. Often, if you’re experiencing backfiring too, it might just be a sign you need to check your coils.

Misfiring and backfiring are indeed common symptoms. I had similar issues last summer—turns out the ignition coil had worn out. A quick replacement fixed it!

Nice to know! How did you know it was the coil for sure? Just curious about how to pinpoint the problem.

I had to check a few things, cjohnson. The lack of power during acceleration was a good clue. Also, it was just one cylinder misfiring, which helped narrow it down.

Ahh, so that’s one way to do it! I had starting issues too. It took a few cranks before it would fire up. Makes me wonder if it’s not just the battery…

That definitely could be a sign of ignition coil trouble! My bike did the same thing before I replaced my coils.

That’s a good way to put it, christinalang! Sometimes the coil issues can feel overpowering. I think it’s important to check them regularly.

I try to keep an eye on mine too, william65. But, honestly, do you think most issues commonly link back to the coil?

13

Definitely, vanessa46! Many riders overlook the ignition system. It’s often the coils causing issues like stuttering or even an unexpected stall in the traffic.

14

That’s good to know! What do you all think about aftermarket coils? Are they worth it, or just a gamble?

15

Good advice! My cringe moment was when I cheaped out on parts… never again!

16

I’ve had mixed results with aftermarket coils. Sometimes they work great; other times, they’re full of issues! I’d stick with OEM unless you’re in a pinch.

And keep in mind the weather can affect coil performance too! If it’s damp, I’ve seen things get particularly tricky.

I’ve been having issues with my ignition coil too. Checking it with a multimeter is a great start! You should measure the resistance to see if it’s within specs. If it’s too high or low, that may be the problem.

Definitely agree! A multimeter can give you concrete numbers. Also, have you tried using a spark tester? It can help confirm if you’re getting a good spark from the ignition coil.
