How to Wire a Push Button Start on a Motorcycle

Adding a push button start to your motorcycle can be a fun and convenient modification. It eliminates the need for a key and allows for a quick and easy start-up. If you’re interested in installing one on your motorcycle, here’s a step-by-step guide to help you wire a push button start.

1. Gather the necessary materials: You’ll need a push button start switch, a relay, wire connectors, electrical tape, and a basic wiring diagram for your motorcycle model.

2. Disconnect the battery: Before you start any electrical work, make sure to disconnect the battery to prevent any accidental shorts or damage.

3. Locate the ignition wires: Find the ignition wires that connect to the ignition switch. They are usually colored red or red with a white stripe.

4. Connect the wires to the relay: Take the ignition wires and connect them to the corresponding terminals on the relay. Use wire connectors to secure the connections and electrical tape to insulate them.

5. Connect the battery wires to the relay: Connect the positive wire from the battery to the positive terminal on the relay. Connect the negative wire from the battery to the negative terminal on the relay.

6. Connect the push button switch: Connect one wire from the push button switch to the positive terminal on the relay. Connect the other wire from the switch to a ground point on the motorcycle frame.

7. Test the connections: Once everything is wired up, reconnect the battery and test the push button start. If it doesn’t work, double-check your connections and wiring.

8. Secure the wiring: After testing, secure the wiring with zip ties or electrical tape to prevent any loose connections or potential damage.

Now that your push button start is wired and working, here are some common questions and answers that may arise during the installation process:
