Suzuki 2005 GSF1200 User Manual

1I-2 Starting System:
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.
• 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.
• 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.
