Replace.
Conductive while it is engaged → Re-
place.
Set the tester selection position to "Ω

CHECKING THE CDI UNIT
Check all electrical components. If no
fault is found, replace the CDI unit.
Then check the electrical compo-
nents again.

STARTING CIRCUIT CUT-OFF
SYSTEM OPERATION
If the main switch is set to "ON", the
starter motor can only operate if at
least one of the following conditions is
met:
• The transmission is in neutral (the
neutral switch is closed).
• The clutch lever is pulled to the han-
dlebar (the clutch switch is closed).
tion
The starting circuit cut-off relay pre-
vents the starter motor from operating
when neither of these conditions has
Ω × 100
been met. In this instance, the start-
ing circuit cut-off relay is open so cur-
rent cannot reach the starter motor.
When at least one of the above con-
ditions has been met the starting cir-
cuit cut-off relay is closed and the
engine can be started by pressing the
start switch.
