ELECTRICAL SYSTEM 6-19
The circuit consists of the turn signal/side-stand relay, neutral indicator light and switches. The ignition coils
will send voltage to the spark plugs dependant on what gear the transmission is in and whether the
side-stand is either up or down. The gear position and side-stand switches work together in this system.
The ignition coils work only in two situations as follows.
1. Transmission: Neutral (ON) Side-stand: Down (OFF)
The current flow A switches “on” the side-stand relay and the ignition coils send voltage to the spark
plugs even when the side-stand is kept down.
2. Side-stand: Up (ON)
The current flow B switches “on” the side-stand relay and the ignition coils send voltage to the spark
plugs. The engine can be started in any gear.
