CHECKING A SWITCH
Use a pocket tester to check the terminals for
continuity. If the continuity is faulty at any
point, replace the switch.
NOTE:
●
Set the pocket tester to “0” before starting
the test.
●
The pocket tester should be set to the “
Ω ×
1”
range when testing the switch for continuity.
●
Turn the switch on and off a few times when
checking it.

CHECKING A SWITCH SHOWN IN THE
MANUAL
The terminal connections for switches (main
switch, handlebar switch, engine stop switch,
light switch, etc.) are shown in a chart similar
to the one on the left.
This chart shows the switch positions in the
column and the switch lead colors in the top
row.
For each switch position, “
” indicates
the terminals with continuity.
The example chart shows that:
There is continuity between red and brown/
blue, and between red and brown when the
switch is set to “ON”.
