When it comes to motorcycle electrical systems, the flasher relay is a crucial component. It allows the turn signals to flash on and off in a rhythmic pattern, indicating the rider’s intentions to other drivers on the road. If you’re looking to install a new flasher relay or troubleshoot an issue with your current one, this article will provide you with a comprehensive guide to motorcycle 2 pin flasher relay wiring diagrams.
What is a Flasher Relay?
Before we dive into the wiring diagram, let’s first understand what a flasher relay is and how it works. A flasher relay is an electromechanical device that controls the turn signals on a motorcycle. When you activate the turn signal switch, it sends an electrical signal to the flasher relay which then sends power to the turn signal bulbs in a rhythmic pattern. This rhythmic pattern is what makes the turn signals “flash” on and off.
Flasher relays come in different types and sizes, but the most common ones are the 2 pin and 3 pin flasher relays. As the name suggests, the 2 pin flasher relay has two pins while the 3 pin flasher relay has three pins. The pins on the flasher relay are used to connect the relay to the motorcycle’s electrical system.
Wiring Diagram for a 2 Pin Flasher Relay
| Pin | Description |
| Pin 1 | Power from the turn signal switch |
| Pin 2 | Power to the turn signals |
The wiring diagram for a 2 pin flasher relay is simple and straightforward. As mentioned earlier, the 2 pin flasher relay has two pins: pin 1 and pin 2. Pin 1 receives power from the turn signal switch, while pin 2 sends power to the turn signals.
Here’s a step-by-step guide on how to wire a 2 pin flasher relay:
- Locate the turn signal switch on your motorcycle.
- Disconnect the wires from the old flasher relay, if there is one.
- Connect the wire from pin 1 on the new flasher relay to the wire that goes to the turn signal switch.
- Connect the wire from pin 2 on the new flasher relay to the wire that goes to the turn signals.
- Test the turn signals to ensure that they are functioning properly.
FAQs
Q: How do I know if my flasher relay is bad?
A: If your turn signals are not flashing, or they are flashing at an irregular rhythm, it may be a sign that your flasher relay is bad. You can use a multimeter to test the continuity of the relay or replace it with a new one to see if that solves the problem.
Q: Do I need a specific type of flasher relay for my motorcycle?
A: Yes, it’s important to use the correct type of flasher relay for your motorcycle. Check your motorcycle’s owner’s manual or consult with a mechanic to determine the appropriate type of relay for your bike.
Q: Can I install a 3 pin flasher relay instead of a 2 pin flasher relay?
A: It’s possible to install a 3 pin flasher relay instead of a 2 pin flasher relay, but you may need to modify the wiring to make it work. It’s best to stick with the type of relay that your motorcycle was designed to use.
Q: Can I install a LED flasher relay on my motorcycle?
A: Yes, LED flasher relays are available for motorcycles and can provide a brighter, more efficient signal. However, you may need to install load resistors to ensure that the turn signals function properly with the new relay.
Q: What if I’m still having issues with my turn signals after installing a new flasher relay?
A: If you’re still having issues with your turn signals after installing a new flasher relay, it’s possible that there is an issue with the wiring or another component in the electrical system. Consult with a mechanic or experienced rider to troubleshoot the problem further.
