CHECK
SWITCH CHECK
Check
the continuity
between the switch terminals
to verify
whether connections
are correct-
To
check
the switch,
read the following
points.
SWITCH CONNECTION
The
table
shown here contains
the
connections
between
the switch terminals (eg main switch,
handlebar switches, brake
switch, light switch
etc).
The column on
the
far
left
shows
the positions of
the
main switch
and
the top
line
indicates the colours
of
the
cables connected
with
the terminals
of the
switch
itself.
o" indicates the terminals
between which
there
is
electrical continuity, ie
a
closed circuit
on
the
respective switch positions.
For example,
in this table:
W
R and
Br"
and
*L
and
L/R" are continuous
when
the
switch
is at
ON.
B
R
and L/R" are continuous
when
the switch
is
at
PARK.

MAIN SWITCH INSPECTION
Before inspecting the switch, see the connection
table
shown above and check
the terminal
connec-
tions
(closed circuit)
by the colour combination.
1.
Detach the main switch connector from
the
harness connector.

When
detaching the connector, do
not pull
by
the cables. This
way
the cables might discon-
nect from the terminals inside the connector
itself.
2.
Check
to see
if
any cables are disconnected
from
their terminal inside
the connector. Re-
connect,
if
necessary.
NOTE:
If
the connector
is
blocked up with
mud
or dust,
clean
it
with a
jet of
compressed
air.
3.
Use the connection
table to
check
the combi-
nation
of
colours
for continuity
(closed
circuit).
in this
example,
continuity
Is
as
follows:
"R and
Br"
and
"L
and
L/R" are
continuous
when
the switch
is at
ON.
"R and
UR*
are continuous
when
the switch
is
at
PARK.
Note
that there
is
no
continuity
(open
circuit)
for
any
of
the combinations of a colour differ-
ent from those mentioned.
4.
Check
the switch
component
for
continuity
between
"R and Br*
and
T
and L7R" and
"R
and L/R\

Control procedure:
•
Repeatedly
shift
the switch
key
to
the various
positions
-

and
P.
•
Shift
the tester selector to 0x1,
•
Connect
the tester positive
cable
(+) to the termi-
nal of
cable

of the
connector, and the negative
cable
