Wiring FLHR Handlebars: A Step-by-Step Guide
Step 1: Disconnect the Battery
Before you begin the wiring process, ensure that the motorcycle battery is disconnected. This is a crucial safety measure that will prevent any electrical short circuits during the wiring process.
Step 2: Remove the Old Handlebars
If you’re replacing your old handlebars, remove them by loosening the handlebar clamp bolts and sliding them off the risers. If you’re installing new handlebars, ensure that they’re compatible with your motorcycle model and have the correct diameter before proceeding.
Step 3: Run the Wires
Run the wires through the handlebars by feeding them through the holes on one end and out through the other. Ensure that each wire is long enough to reach the respective connectors on the other end.
Step 4: Make Connections
Connect the wires according to the FLHR handlebars wiring diagram. Use crimp connectors or soldering to ensure a secure connection. Test each connection with a multimeter to ensure proper voltage and continuity.
Step 5: Secure the Wires
Secure the wires with electrical tape or zip ties to prevent them from rattling or moving inside the handlebars. Ensure that they don’t interfere with the motorcycle controls or the steering.
Step 6: Reconnect the Battery
Once you’ve completed the wiring process, reconnect the motorcycle battery and test the electrical system. Ensure that the handlebar switches and accessories function properly.
FAQs
Q: What’s the difference between handlebar risers and handlebar clamps?
A: Handlebar risers are used to increase the height of the handlebars, while handlebar clamps secure the handlebars to the risers or the triple tree.
Q: Can I wire my FLHR handlebars without a wiring diagram?
A: It’s not recommended to wire your handlebars without a wiring diagram, as this can lead to improper connections that can damage the motorcycle’s electrical system.
Q: What’s the best way to secure the wires inside the handlebars?
A: You can use electrical tape or zip ties to secure the wires inside the handlebars. Ensure that they don’t interfere with the motorcycle controls or the steering.
Q: Can I use any handlebars on my FLHR motorcycle?
A: No, it’s important to ensure that the handlebars you use are compatible with your FLHR motorcycle model and have the correct diameter, as this can affect the motorcycle’s handling and maneuverability.
Q: What’s the recommended gauge for FLHR handlebar wires?
A: The recommended gauge for FLHR handlebar wires is 16 to 20 AWG. Thicker wires can lead to difficulty in handling and installation, while thinner wires can’t handle the electrical load of the handlebar switches and accessories.
Conclusion
Wiring FLHR handlebars can be a challenging task, but with this comprehensive guide, you can ensure proper connections and a smooth electrical system. Always refer to the FLHR handlebars wiring diagram when wiring your handlebars to prevent any damage to your motorcycle’s electrical system. If you’re unsure of your wiring skills, it’s always recommended to seek professional help.
