If you own a Harley Davidson motorcycle, you know that a faulty starter can be a frustrating issue. When you turn the key, and the engine doesn’t start, it can be discouraging. However, before you take your bike to the shop, there are a few simple troubleshooting steps that you can take to diagnose and fix the problem.
Understanding the basics of Harley Davidson starters is the first step in troubleshooting. The starter system of a Harley Davidson motorcycle consists of several components, including the battery, starter motor, starter solenoid, and starter relay. Each of these components must be in good working order for the starter to function correctly. If any of these parts fail, it can cause the starter to malfunction.
Initial troubleshooting steps involve checking the battery, fuses, and connections. A dead battery is one of the most common causes of starter problems. If the battery is fully charged, the fuses are good, and the connections are tight, the problem may be with the starter motor, starter solenoid, or starter relay. In this case, more advanced diagnostic procedures may be necessary.

Understanding the Basics of Harley Davidson Starters
If you’re experiencing problems with your Harley Davidson starter, then it’s important to understand the basics of the starter system. This will help you diagnose and fix any issues you may be having.
Components of the Starter System
The starter system on a Harley Davidson consists of several components that work together to turn the engine over. These components include:
- Starter motor: This is the main component of the starter system. It’s responsible for turning the engine over when you press the starter button.
- Starter relay: The starter relay is a small electrical component that sends power to the starter motor when you press the starter button.
- Battery: The battery provides the power needed to turn the engine over.
- Starter solenoid: The starter solenoid is responsible for engaging the starter motor with the engine’s flywheel.
Common Symptoms of Starter Problems
If you’re experiencing problems with your Harley Davidson starter, then you may notice one or more of the following symptoms:
- Clicking sound when you press the starter button: This could be a sign that there’s a problem with the starter relay or starter motor.
- Engine won’t turn over: If you press the starter button and the engine won’t turn over, then there could be a problem with the starter motor, battery, or starter solenoid.
- Slow cranking: If the engine is turning over slowly, then this could be a sign that the battery is low or there’s a problem with the starter motor.
By understanding the basics of the Harley Davidson starter system and the common symptoms of starter problems, you’ll be better equipped to diagnose and fix any issues you may be having.
Initial Troubleshooting Steps
If you are experiencing issues with your Harley Davidson starter, there are a few initial troubleshooting steps you can take to identify the problem. Before you start, make sure you have the necessary tools, including a multimeter and a service manual.
Inspecting the Battery Condition
The first step is to inspect the battery condition. A weak or dead battery can cause starter problems. Check the battery terminals for any signs of corrosion or loose connections. If you notice any corrosion, clean the terminals with a wire brush and apply a thin layer of dielectric grease to prevent future corrosion. Use a multimeter to test the battery voltage. A fully charged battery should read around 12.6 volts. If the voltage is low, recharge or replace the battery.
Checking the Starter Relay
The starter relay is responsible for sending power to the starter motor. If the relay is faulty, the starter motor won’t receive power, resulting in starter problems. Check the starter relay for any signs of damage or corrosion. Use a multimeter to test the continuity of the relay. If the relay is faulty, replace it with a new one.
Evaluating Wiring and Electrical Connections
Wiring and electrical connections play a critical role in the starter system. Check all wiring and connections for any signs of damage or corrosion. Use a multimeter to test the continuity of the wiring. If you notice any issues, repair or replace the wiring or connections as necessary.
By following these initial troubleshooting steps, you can identify and fix most Harley Davidson starter problems. If the issue persists, refer to the service manual or seek professional assistance.
Diagnosing Starting Issues
If you’re having trouble starting your Harley Davidson, there are a few things you can do to diagnose the problem. Before you start, make sure your battery is fully charged and your fuel tank is full. Then, follow these steps:
Intermittent Starting Problems
If your bike is starting intermittently, it could be due to a number of issues. One common cause is a loose or corroded connection in the starter circuit. Check all the connections and make sure they are tight and clean. Another possible cause is a faulty starter relay. You can test this by using a multimeter to check the resistance across the relay contacts.
Identifying Grinding or Clicking Noises
If you hear a grinding or clicking noise when you try to start your bike, it could be due to a problem with the starter motor or the starter clutch. Check the starter motor for signs of wear or damage, and make sure it is spinning freely. If the starter motor is fine, the problem may be with the starter clutch. This is a more complicated repair and may require the help of a professional mechanic.
Testing the Ignition Switch and Start Button
If your bike isn’t starting at all, it could be due to a problem with the ignition switch or start button. Check the ignition switch for signs of wear or damage, and make sure it is functioning properly. You can test the start button by using a multimeter to check the resistance across the contacts when the button is pressed.
Remember, troubleshooting starting issues can be a complicated process, and it may take some time to diagnose the problem. If you’re unsure about any of the steps, or if you’re not comfortable working on your bike, it’s always best to seek the help of a professional mechanic.
Advanced Diagnostic Procedures
If you’re still having trouble with your Harley Davidson starter, there are some advanced diagnostic procedures you can perform to pinpoint the issue.
Using a Service Manual for In-Depth Troubleshooting
One of the most important tools you can have when diagnosing starter problems is a service manual. This will provide you with detailed information on your motorcycle’s electrical system, as well as step-by-step instructions for troubleshooting and repair. Be sure to consult your service manual before attempting any advanced diagnostic procedures.
Performing Voltage Drop Tests
Voltage drop tests can help you determine whether there is excessive resistance in the starter circuit. To perform this test, you’ll need a multimeter. First, connect the multimeter to the battery terminals and record the voltage. Then, connect the multimeter to the starter motor terminal and the starter solenoid terminal. Crank the engine and record the voltage readings. If the voltage drop is greater than 0.5 volts, there may be an electrical problem in the starter circuit.
Checking the Starter Solenoid and Motor
If you’ve ruled out other potential causes of starter problems, it may be time to check the starter solenoid and motor. To do this, you’ll need to remove the starter from your motorcycle and perform a bench test. Connect the starter to a fully charged battery using jumper cables. If the starter spins freely and produces a healthy spark, it’s likely that the issue lies elsewhere in the starter circuit. If the starter fails this test, you may need to replace it.
By using these advanced diagnostic procedures, you’ll be able to identify and resolve starter problems on your Harley Davidson motorcycle. Remember to always consult your service manual and exercise caution when working with electrical systems.
Repair and Replacement Solutions
If you’re experiencing issues with your Harley Davidson starter, you may need to consider repair or replacement options. In this section, we’ll go over when to repair vs. replace the starter, a step-by-step starter replacement guide, and upgrading the starter system.
When to Repair vs. Replace the Starter
If you’re experiencing minor issues with your starter, such as a clicking sound or slow cranking, it may be possible to repair the starter. However, if your starter is completely dead or has major issues, replacement may be necessary.
When deciding whether to repair or replace your starter, consider the cost. In some cases, it may be more cost-effective to replace the starter rather than repair it. Additionally, if your starter is old and has already been repaired multiple times, replacement may be the better option.
Step-by-Step Starter Replacement Guide
