CHECKING THE BULBS AND BULB SOCKETSELEC
WARNING
EAS00732
CHECKING THE BULBS AND
BULB SOCKETS
Check each bulb and bulb socket for damage or
wear, proper connections, and also for continu-
ity between the terminals.
Damage / wear Repair or replace the bulb,
bulb socket or both.
Improperly connected Properly connect.
No continuity Repair or replace the bulb, bulb
socket or both.
TYPES OF BULBS
The bulbs used on this motorcycle are shown in
the illustration on the left.
Bulbs
A and B are used for the headlights
and usually use a bulb holder that must be
detached before removing the bulb. The ma-
jority of these types of bulbs can be removed
from their respective socket by turning them
counterclockwise.
Bulbs
C are used for turn signal and
tail / brake lights and can be removed from
the socket by pushing and turning the bulb
counterclockwise.
CHECKING THE CONDITION OF THE
BULBS
The following procedure applies to all of the
bulbs.
1. Remove:
bulb
Since the headlight bulb gets extremely
hot, keep flammable products and your
hands away from the bulb until it has
cooled down.
When changing the tail / brake light bulb,
confirm that the frame has cooled accord-
ing to the warning label and change the
tail / brake light bulb.

NOTE:
WARNING
Pocket tester
90890-03112, YU-3112
Check each bulb socket for continuity in the
same manner as described in the bulb section;
however, note the following.
a. Install a good bulb into the bulb socket.
b. Connect the pocket tester probes to the re-
spective leads of the bulb socket.
c. Check the bulb socket for continuity. If any of
the readings indicate no continuity, replace
the bulb socket.
CHECKING THE LEDs
The following procedures applies to all of the
LEDs.
1. Check:
LED (for proper operation)
Improper operation Replace.
a. Disconnect the meter assembly coupler (me-
ter assembly side).
b. Connect two jumper leads
1 from the bat-
tery terminals to the respective coupler ter-
minal.
As for connecting with which coupler terminal,
refer to “CABLE ROUTING” in chapter 2.
A wire that is used as a jumper lead must
have at least the same capacity of the bat-
tery lead, otherwise the jumper lead may
burn.
This check is likely to produce sparks,
therefore, make sure no flammable gas or
fluid is in the vicinity.
c. When the jumper leads are connected to the
terminals the respective LED should illumi-
nate.
Does not light Replace the meter assem-
bly.

3. Starter motor
Connect the positive battery terminal and
starter motor lead with a jumper lead .
Repair or replace the
starter motor. A wire that is used as a jumper lead
must have at least the same capacity or
more as that of the battery lead, other-
wise the jumper lead may burn.
This check is likely to produce sparks,
therefore make sure nothing flammable
is in the vicinity.

FUEL PUMP SYSTEMELEC
WARNING
EAS00819
CHECKING THE FUEL PUMP
Gasoline is extremely flammable and under
certain circumstances there can be a danger
of an explosion or fire. Be extremely careful
and note the following points:
Stop the engine before refueling.
Do not smoke, and keep away from open
flames, sparks, or any other source of fire.
If you do accidentally spill gasoline, wipe it
up immediately with dry rags.
If gasoline touches the engine when it is
hot, a fire may occur. Therefore, make sure
the engine is completely cool before per-
forming the following test.
1. Check:
Fuel pump operation
a. Insert the plug
1 to fuel return hose end.
b. Fill the fuel tank.
c. Put the end of the fuel hose into an open con-
tainer.
d. Connect the battery (DC 12 V) to the fuel
pump coupler as shown.
Positive battery lead red / blue
2
Negative battery lead black 3
e. If fuel flows out of the fuel hose, the fuel pump
is OK. If fuel does not flow, replace the fuel
pump.
