SG250 Ownerās and Service Manual

Maintenance Manual addresses the SG250 electric start system.
If your SG250 does not start when you press the starter button, the first thing you should check is the
engine kill switch to make sure it is in the run position.
If the kill switch is in the run position and the motorcycle
does not crank at all, the next thing to check is the fuse. The
fuse is accessible underneath the left body panel.
If the fuse is open (blown), you will need to replace it, but before you do, you should find the reason
the fuse opened. If you do not, you will just blow the fuse again when you replace it. Examine all
wiring and use a multimeter to identify any shorts to ground.
If the fuse is intact and the motorcycle does not crank, next
check the battery. Please see our battery maintenance
tutorial for this.
If the battery output is appropriate and the connections are
in good shape, check the starter solenoid. Use a multimeter
to confirm voltage is reaching the relay and the relay closes
when the starter button is pressed. If the starter relay does
not receive voltage when the starter button is pressed, the
problem is in the circuit from the starter button. Use a
multimeter to isolate the fault and correct any anomalies. If
the starter relay receives electrical energy but it does not
close the circuit to the starter, check the starter solenoid
connections. If they are intact and free of corrosion, replace
the starter solenoid. Please call us at 909 445 0900 if you
need a starter solenoid.
