Book Excerpt: 1989-2008 Suzuki GS500, GS500E, GS500F Twins Repair Manual GENERAL INFORMATION

All models have a 12-volt electrical system. The components include a three-phase alternator unit and combined regulator/rectifier unit. The regulator maintains the charging system output within the specified range to prevent overcharging, and the rectifier converts the ac (alternating current) output of the alternator to DC (direct current) to power the lights and other components and to charge the battery. The alternator rotor is driven by the crankshaft. The starter motor is mounted on the crankcase behind the cylinders. The starting system includes the starter motor, the battery, the relay and the various wires and switches. If the engine stop switch and the ignition (main) switch are both in the "Run" or "On" position, the starter relay allows the starter motor to operate only if the transmission is in neutral (neutral switch on) or, if the transmission is in gear, if the clutch lever is pulled into the handlebar (clutch switch on, where fitted) and the sidestand is up. Note: Keep in mind that electrical parts, once purchased, cannot be returned. To avoid unnecessary expense, make very sure the faulty component has been positively identified before buying a replacement part.
