Common Turn Signal Symptoms

You may notice one or more of the following:

• One front signal not working
• A rear signal appearing dim
• Only one side functioning correctly
• Signals failing to blink or blinking inconsistently

Before replacing bulbs or wiring, follow the checks below.

Step 1: Check the Flasher Relay

What it does

The flasher relay controls the blinking behavior of the turn signals.

If loose, it can cause:

• No signals
• Dim signals
• Intermittent blinking

How to check

1. Power the bike off.
2. Remove a side panel.
3. Locate the small black box inside the bike.
4. Find the short wire labeled “FLASHER.”
5. Identify the small module plugged into it (looks like a flash drive).
6. Ensure it is fully seated.

Test

1. Power the bike on.
2. Activate the turn signals.
3. Gently wiggle the relay connection.

If signals start working, the issue was a loose connection.

Preventative fix

• If the connector feels loose, secure it with electrical tape
• Position it so vibration cannot pull it loose

Step 2: Check Turn Signal Harness Connectors

If the relay is secure, inspect the main signal connectors.

How to check

1. Open the side panels.
2. Locate the white and orange connectors for the turn signals.
3. Unplug both connectors.

What to inspect

• Male and female pins should be:
  • Clean
  • Straight
  • Free of corrosion or debris

Water exposure can cause:

• Corrosion
• Poor contact
• Dim or non-functioning signals

The photos provided are examples of water-damaged pins.

Resolution

• If dirty: clean gently and reconnect
• If bent: carefully realign
• If heavily corroded or damaged: connector may need replacement

Reconnect securely after inspection.

Step 3: Final Check

After completing both checks:

• Confirm all signals blink evenly
• Confirm brightness is consistent front and rear
• Reinstall all panels securely
