ENGINE STARTING CIRCUIT
Operation During Start Process
Turn key switch (6) to ―ON‖ position, connect terminal ―B‖ and ―BR‖, output electric current starts power relay
(8), then fuse box is power on. Make control handle gear in neutral positionrelay10is power on and
get through 87aand30
Then key switch (6) is turned to ―ON‖ position, terminal ―R2‖ and ―B‖ are connected, starter relay (4) is
started, then other contact terminals ―B‖ and ―PP‖ are connected, active gear of starter (3) is propelled to
contact ring gear of flywheel and connect with contact terminal of starter.
Electric current comes out from storage battery (2), goes through terminal ―B‖ and ―PP‖ of starter relay (4)
and arrives at starter (3) terminal ―50‖.
Operation After Start Process
Once generator is started, the belt will drive AC generator (9) to create electric current. Electric current goes
