of the groove on the bottom of the pulley.
5. VISUALLY CHECK GENERATOR WIRING
(a) Check that the wiring is in good condition.
6. LISTEN FOR ABNORMAL NOISES FROM GENERATOR
(a) Check that there is no abnormal noise from the generator while the engin\
e is running.
7. INSPECT CHARGE WARNING LIGHT CIRCUIT
(a) Turn the ignition switch ON. Check that the charge warning light comes on\
.
(b) Start the engine and check that the light goes off.
HINT:

ing light circuit. 8. INSPECT CHARGING CIRCUIT WITHOUT LOAD
(a) According to the following procedure, connect an amme-
ter and voltmeter as shown in the illustration.
(1) Disconnect the wire from terminal B of the generatorand connect it to the negative (±) lead of the amme-
ter.
(2) Connect the positive (+) lead of the ammeter to ter- minal B of the generator
(3) Connect the positive (+) lead of the voltmeter to ter- minal B of the generator.
(4) Ground the negative (±) lead of the voltmeter.
(b) Check the charging circuit. (1) Keep the engine speed at 2,000 rpm, check thereading on the ammeter and voltmeter.

ADJUSTMENT
1. HEADLIGHT AIM ONLY
HINT:

Perform aiming adjustment with Low±beam.

Since the Low±beam light and the High±beam light is a
unit, if aiming on either side is connect, the other side
should also be connect.
However, check both beams just to make sure.
(a) Prepare vehicle in the following conditions.

Check that any damage or deformation does not exist on
the body around the headlights.

Fuel tank is full.

The tire inflation pressure is at the specified level.

Vehicle is parked at a level surface.

A person having an average weight sits in the driver's
seat.

Vehicle is bounced up and down to stabilize the suspen-
sion to the normal position.
(b) Prepare a thick white paper (Draw base lines).
HINT:

Stand the paper perpendicular as against a wall.

The base lines differ for ºLow±beam inspectionº and
ºHigh±beam inspectionº.
(1) V line (Vehicle Center position) Draw a vertical line down the center of the paper in
order to align it with the center of the vehicle.
(2) H line (Headlight height)
Draw horizontal line across the paper at the same
height from the ground as the center mark for the
Low±beam lights.
(3) V LH line, V RH line (Center mark position of right and left headlights)
Draw vertical lines, for left & right, at the same posi-
tion as the center mark for the Low±beam lights.
HINT:
Follow the same procedures when adjusting the High±beam
lights.

(c) Check the headlight aiming. (1) Align the paper with the center of the vehicle.

Make a distance of 3 m ( 9.84 ft) between the head-
lights and the paper, and put the paper against a
wall with the H line being at the same height as the
center mark.

Align the center of the vehicle with the V line on the
paper, and ensure that the paper is at a 90  angle
in accordance to the V line.
(2) Start the engine.
(3) Turn on the headlights and check that the aim is with in the specified valves shown in the illustration.
NOTICE:

When covering the headlights, finish it within 3 mi-
nuites.

The headlight lens is made of synthetic resin, so it is
easily.
HINT:
When checking the aiming of the High±beam, shut off the Low±
beam or disconnect the Low±beam headlight connector.
(d) Adjust the aim in the vertical direction: Using a screwdriver, adjust the headlight aim within the
specified range by turning the aiming screw A.
NOTICE:

Adjust the headlight aim by turning the screw in the
tightening direction.

When the screw is tightened excessively, loosen it
once and re±tighten it to adjust the headlight aim.
HINT:
The optical axis aim moves downward when turning the screw-
driver clockwise, and it moves upward when turning the screw-
driver counterclockwise.
(e) Adjust the aim in the horizontal direction: Using a screwdriver, adjust the headlight aim within the
specified range by turning the aiming screw B.
NOTICE:

Adjust the headlight aim by turning the screw in the
tightening direction.

When the screw is tightened excessively, loosen it
once and re±tighten it to adjust the headlight aim.
