Symptoms of a Bad Harley LED Turn Signal

We’ve noticed that a bad Harley LED turn signal can be identified by symptoms such as blinking stopping after turning on the turn signal and the indicator panel no longer lighting up.

These are common causes of turn signal malfunction that Harley riders often face. Some of the main issues include a change in flashing rate, turn signal lights not turning off, and turn signal lights failing to flash.

The change in flashing rate can occur due to incorrect bulb replacement, burned out bulbs, bad power connections, or loose turn switch connections.

On the other hand, the failure of turn signal lights to turn off can be caused by a damaged or faulty cancelling finger inside the switch, a faulty cancelling cam or clock spring, or specific solutions depending on the Harley Davidson model.

It’s crucial to consult the owner’s manual or seek professional help if uncertain to avoid further problems.

Common Harley Davidson LED Turn Signal Problems

One possible cause of a change in flashing rate is if the bulb replacement was not done correctly. This is a common issue with Harley LED turn signals. Other common problems include turn signal lights not responding, failing to flash, or not turning off.

These issues can be caused by burned out bulbs, bad power connections, or loose turn switch connections. In some cases, the battery may be excessively charged or undercharged.

To troubleshoot these problems, it is important to check the bulbs, power connections, and turn switch connections. If unsure or to avoid further problems, it is recommended to consult the owner’s manual or seek professional help.

LED turn signal troubleshooting requires technical knowledge, but with the right tools and understanding, most Harley owners can remove or replace a faulty turn signal module.

Possible Causes of Change in Flashing Rate

To determine the cause of a change in flashing rate, we can start by checking if the bulb replacement was done correctly. If the bulbs were not properly installed or if they are burned out, it can result in a slow flashing rate.

To troubleshoot a fast flashing rate, we should inspect the power connections and the turn switch connection for any looseness. Another possible cause could be an excessively charged or undercharged battery.

In the case of a slow flashing rate, possible solutions include ensuring that the bulb replacement was done correctly and checking for any loose power connections. It is also important to check if the bulbs are burned out.

If these steps do not resolve the issue, it is recommended to seek professional help to avoid further problems.

Possible Causes of Turn Signal Lights Not Turning Off

Let’s address the possible causes of the turn signal lights not turning off.

  • Damaged or faulty cancelling finger inside the switch
  • Faulty cancelling cam or clock spring
  • Varying solutions depending on the Harley Davidson model

When troubleshooting the turn signal switch, it is important to consult the owner’s manual for a better understanding of the problem and the necessary tools required. If unsure or to avoid further complications, seeking professional help is recommended.

To fix this issue, start by checking the cancelling finger inside the switch for any damage or faults. If the finger is damaged, it may not be able to properly cancel the turn signal lights.

Additionally, inspect the cancelling cam or clock spring as they could also be causing the lights to stay on. Keep in mind that different Harley Davidson models may have different solutions, so it’s important to consult the manual for specific instructions.
