However, success is short-lived, as the motorcycle cannot be driven at this time. Up to this point the ignition module connection to ground has been provided by a combination of the clutch lever safety switch position and the gear selector safety switch position. | However, success is short-lived, as the motorcycle cannot be driven at this time.

The problem arises as the clutch lever is pulled in (clutch lever safety switch changes position - connects to ground), the transmission is shifted out of neutral and into gear (gear selector safety switch opens - no connection to ground), and the clutch lever is slowly released (the clutch lever safety switch changes position - connects to the gear selector safety switch), disconnecting the ground connection to the ignition module enable circuit | The problem arises as the clutch lever is pulled in (clutch lever safety switch changes position - connects to ground), the transmission is shifted out of neutral and into gear (gear selector safety switch opens - no connection to ground), and the clutch lever is slowly released (the clutch lever safety switch changes position - connects to the gear selector safety switch), disconnecting the ground connection to the ignition module enable circuit and stopping the engine. | ||
This is where the sidestand comes into play; with the sidestand in the down (parked) position, the sidestand safety switch is open (no connection to ground). When the sidestand is raised to the up (riding) position, the sidestand safety switch closes (connecting to ground) and completes the ignition module enable circuit, allowing the motorcycle to be driven. As the sidestand safety switch is only a component of the run circuit, and not a component of the start circuit, the position of the sidestand is not relevant when diagnosing starting problems. | This is where the sidestand comes into play; with the sidestand in the down (parked) position, the sidestand safety switch is open (no connection to ground).
