When turning the key switch to the start position, which three wires are connected?

In the context of the wiring associated with a key switch in Yamaha systems, when the key switch is turned to the start position, it typically connects the red (which commonly symbolizes a positive power lead), the brown, and the yellow wires. The red wire often provides power to the ignition circuit, while the brown wire may connect to the starter relay or solenoid, and the yellow wire can serve as a signal to engage the starting process.

The combination of these wires ensures that the electrical flow necessary to initiate the starting process is correctly established. Understanding the role of each wire is crucial for diagnosing issues related to starting problems, as a lack of connection in any of these wires could result in the engine not starting.

Recognizing the correct pairing of wires in this scenario is essential for performing accurate troubleshooting and repairs in Yamaha vehicles.
