2. ADJUST HEADLIGHT AIM ONLY
(a) Place the vehicle in the following conditions.

The area around the headlight is not deformed.

The vehicle is parked on a level surface.

Tire inflation pressure is the specified value.

A driver is in the driver's seat and the vehicle is in a state ready for driving (with a tank full).

The vehicle has been bounced several times.
(b) Check the headlight aiming.
(1) Prepare a thick white paper.
(2) Stand the paper perpendicular to the ground at the position 9.84 ft away from the headlights.
(3) Ensure that the center line of the vehicle and the paper face forms a 90-degree angle as shown
in the illustration.
(4) Draw a horizontal line (H line) on the paper, showing where the headlights should strike.
(5) Draw a vertical line (V line) to where the center line of the vehicle is to be.
(6) Draw 2 vertical lines (by connecting the low and high beam center marks) to where the both head-
lights should strike (V RH and V LH lines).
(7) Draw a horizontal line (by connecting the both low beam center marks) to where the headlights
should strike (H RH and H LH lines).
HINT:
The H RH and H LH line is 0.4° below the horizontal line (H line) of the light axis.
(8) Start the engine.
(9) Turn the headlights ON.
(10) Check that the headlights properly strike the position shown in the illustration.
(11) If not, adjust the lights in the vertical direction.
HINT:
As shown in the illustration, adjust each aim of the RH and LH lights.
(c) When adjusting it in the vertical direction:
Using adjusting bolt, adjust the headlight aim to within the specified range.

If the voltmeter reading is more than standard voltage, replace
the voltage regulator.
If the voltmeter reading is less than standard voltage, check the
voltage regulator and generator as follows:

With terminal F grounded, start the engine and
check the voltmeter reading of terminal B.

If the voltmeter reading is more than standard volt-
age, replace the voltage regulator.

If the voltmeter reading is less than standard volt-
age, check the generator.
9. INSPECT CHARGING CIRCUIT WITH LOAD
(a) With the engine running at 2,000 rpm, turn on the high
beam headlights and place the heater blower switch at
ºHIº.
(b) Check the reading on the ammeter.
Standard amperage: 30 A or more
If the ammeter reading is less than the standard amperage, re-
pair the generator.
HINT:
If the battery is fully charged, the indication will sometimes be
less than standard amperage.
