Power

before

contact

is

supplied

at

pin

2

of

the

lighting

switch

(C622).

If

a

connection

is

made

to

switch

C622

(contacts

2

and

1),

a

voltage

is

applied

to

contact

1

of

relay

G

000

(tail

light/width

marker

light

relay)

via

w

ire

2100.

Once

the

relay

is

energised,

a

connection

is

made

between

points

3

and

5.

As

a

result,

a

voltage

is

applied

through

relay

G000

(contacts

3

-

5),

w

ire

2101,

fuse

E283

and

wire

2169

to

pin

2

of

switch

C

871

(potentiometer

for

headlamp

height

adjustment).

V

ia

the

same

wire,

power

is

also

supplied

to

pin

1

of

the

headlamp

height-adjustment

motor

on

the

left

(B129)

and

right

(B130).

When

the

headlamp

height

switch

is

operated,

the

voltage

at

pin

1

of

the

switch

will

change,

so

that

the

headlamp

height

adjustment

motors

on

the

left

(B129)

and

right

(B130)

will

be

activated

via

wire

4953

at

pin

3.

Depending

upon

the

position

of

C

871

(headlamp

height

adjustment

potentiometer),

the

m

otor

in

the

headlamp

w

ill

be

activated.

This

will

continue

until

electrical

equilibrium

is

achieved.

This

equilibrium

refers

to

the

voltage

dif

ference

that

exists

between

wires

2169

and

4953

of

C871,

B129

and

B130.

The

voltage

dif

ference

should

be

the

same

for

all

three

components.
