STARTER SYSTEM
DESCRIPTION
The starter system is shown in the diagram below: namely, the starter motor, starter relay, starter button, clutch
switch, ignition switch and battery.
Depressing the starter switch(on the right handlebar switch box) energizes the relay, causing the contact points
to close which connects the starter motor to the battery. The motor draws about 70 amperes to start the engine.
