If the bulbs and fuse are in good condition, the next step is to test the turn signal switch.
- Access the Switch: Depending on the model, you may need to remove a cover or panel.
- Perform a Functional Test: Use a multimeter to check the continuity of the switch when toggled. A lack of continuity signals a faulty switch that needs replacement.
Step 4: Inspect for Wiring Issues
After checking the switch, inspect the wiring connected to the turn signals.
- Check for Damage: Inspect all wiring for wear, fraying, or corrosion.
- Look for Loose Connections: Make sure all connectors are securely attached. Re-secure any loose connections, and clean off any corrosion.
Step 5: Test the Relay
If everything else checks out but the turn signals still aren’t functioning, the relay may be the culprit.
- Locate the Relay: Refer to your motorcycle’s service manual for the relay’s location.
- Conduct a Relay Test: Some relays can be tested by swapping with another relay of the same type that you know is working. If the signals begin to work, the relay is confirmed faulty.
Preventive Maintenance for Your Harley’s Turn Signals
Once you’ve resolved any issues with your turn signals, it’s a good idea to implement preventive maintenance practices to keep everything in optimal working condition.
