Common Harley Davidson Starter Problems and Solutions

Alright, let's get down to the nitty-gritty. Now that we understand the basics, we'll look at the common Harley Davidson starter problems. We'll also provide some solutions to get your bike back on the road. Remember, safety first! Always disconnect the negative battery cable before working on any electrical components.

Weak Battery or Dead Battery

One of the most common causes of Harley Davidson starter problems is a weak or dead battery. This is pretty common, especially if the bike has been sitting for a while, or if you have a lot of electrical accessories draining the battery. If you turn the key and only hear a clicking sound, or if the starter struggles to crank the engine, the battery is the likely culprit.

Solutions:

• Battery Testing: Use a multimeter to check the battery voltage. A fully charged battery should read around 12.6 volts or higher. If it's significantly lower, the battery needs to be charged or replaced. If you don't have a multimeter, you can have your battery tested at an auto parts store.
• Charging: Connect the battery to a battery charger and let it charge fully. Follow the charger's instructions. If the battery doesn't hold a charge, it may need to be replaced.
• Battery Maintenance: Regularly inspect and maintain your battery. Clean the terminals of any corrosion. This will ensure good electrical contact. Consider using a battery tender to keep the battery charged when the bike is not in use.

Faulty Starter Solenoid

The starter solenoid is a crucial component that acts as a switch, delivering power from the battery to the starter motor. If the solenoid fails, the starter won't engage. Symptoms of a faulty solenoid include a clicking sound when you press the starter button, but no cranking, or a starter that intermittently fails to engage.

Solutions:

• Testing: Locate the solenoid (usually mounted on the starter motor). You can test it by jumping the two large terminals with a screwdriver. If the starter engages when you do this, the solenoid is likely faulty. But be extremely cautious when you do this, there will be sparks involved, so make sure you are in a well-ventilated area.
• Replacement: The solenoid can usually be replaced without replacing the entire starter motor. Purchase a replacement solenoid compatible with your Harley Davidson model.

Worn Starter Motor Brushes

Inside the starter motor, brushes are essential for transferring electricity to the motor's armature. Over time, these brushes wear down, leading to poor performance or failure. You can recognize this issue by sluggish cranking or intermittent starting issues.

Solutions:

• Inspection: The starter motor must be removed from the bike to inspect the brushes. Examine the brushes for wear and tear. If they are worn down, they will need replacing.
• Replacement: Starter brushes are available as a replacement part for most Harley Davidson starter motors. Replace the brushes according to the manufacturer's instructions.

Loose or Corroded Wiring Connections

Electrical connections can corrode or come loose over time, especially in a motorcycle that is exposed to the elements. Loose or corroded connections can interrupt the flow of electricity to the starter motor. This can manifest as intermittent starting problems or a complete failure to start.

Solutions:

• Inspection: Carefully inspect all wiring connections related to the starter system. These include the battery terminals, solenoid connections, and starter motor connections. Look for corrosion, loose connections, or damaged wires. Disconnect each connection and clean them with a wire brush or electrical contact cleaner.
• Tightening and Repair: Tighten any loose connections. If you find damaged wires, replace them or repair them properly using solder and heat shrink tubing.

Other Potential Problems

While the above issues are the most common, other factors can also contribute to Harley Davidson starter problems. Understanding these less common issues can help in the troubleshooting process. For example, a faulty ignition switch can prevent power from reaching the starter solenoid. Check the ignition switch by testing for power at the solenoid with the key in the start position. If there's no power, the ignition switch might be the issue. Also, issues with the engine's internal components, such as low compression, can make starting difficult. Perform a compression test to check the engine's health. Additionally, a faulty starter relay can prevent the starter from engaging. The starter relay is an electrical switch that controls the power to the starter solenoid. If the relay fails, the starter motor will not engage. Replace the relay if it is faulty.
