is

supplied

to

the

reversing

light

switch

(E501)

via

E

018

and

wire

1217.

This

to

the

reversing

lights

(C026/C027)

and

drawn

vehicle

A

001.

The

reversing

buzzer

(B176)

can

only

be

Position

1

(“town

lights”)

By

switching

the

lighting

switch

(C622)

to

the

1st

position

(connection

between

contacts

2

and

1),

relay

G000

is

activated

through

wire

2100.

Relay

G

000

provides

power

to

the

marker

lights

and

tail

lights

and

to

the

fog

lamps

switch

(C727),

pins

1

and

2.

This

is

done

via

fuse

E

285,

wire

2639.

There

is

also

a

connection

via

the

same

fuse

and

wire

to

the

V

IC

(pin

C7/745)

for

the

“light

on”

buzzer

(in

D

IP).

Position

2

(“dipped

b

eam”)

By

switching

the

lighting

switch

(C622)

to

the

2nd

position

(connection

between

contacts

2

and

4),

relay

G001

is

energised

through

wire

21

10.

Power

for

the

dipped

(C000)

and

the

is

supplied

via

fuse

E004

and

wire

21

C001

is

supplied

w

C

775

is

supplied

w

power

before

contact

at

pin

B3.

T

his

is

used

for

signalling.

During

signalling,

points

B

B4

are

connected

to

his

is

a

spring-loaded

connection.

Relay

G

2120.

Relay

G002

supplies

power

to

the

(C002/C003)

via

fuse

E

006,

through-connection

G743

and

wire

2122.

Wire

2122

is

also

connected

to

pin

C6/745

of

the

VIC

and

the

spotlights

(C006/C007).

T

he

VIC

switches

on

the

“main

beam”

indicator

in

the

DIP

via

the

I-CAN.

Diode

D610

prevents

voltage

from

getting

to

relays

G000

and

G001

through

connection

A4

when

the

m

ain

beam

switch

is

pulled

back

further

during

signalling.

Otherwise

this

would

activate

all

the

other

lights

during

signalling.

(C775)

are

connected

to

each

other

.

Pin

A

4

is

supplied

w

power

via

diode

D610

when

light

switch

C622

is

turned

to

position

2.

Relay

G

and

G001

are

directly

activated

via

E

282.

As

a

result,

the

dipped
