When

is

energised,

a

connection

is

made

between

and

a

If

turned

to

the

“s

a

contact

is

m

ade

in

this

switch

between

and

The

power

is

now

supplied

from

the

batteries

through

fuse

E037,

the

connection

1-2

from

the

ignition/starter

switch

and

wire

4004

on

connection

point

of

D979.

A

voltage

is

also

applied

to

connection

point

30

of

relay

G

185

through

wire

4004.

Relay

G

185

is

only

fitted

if

the

vehicle

is

equipped

with

AS

Tr

onic.

When

the

contact

is

switched

on

and

the

gearbox

is

in

neutral,

relay

G

185

will

be

energised.

The

voltage

is

now

applied

to

connection

point

85

of

relay

G

203

through

wire

4004,

contacts

30-87

of

relay

G

185,

contacts

3-5

of

relay

G372.

This

relay

is

energised,

thereby

connecting

connection

point

30

to

connection

point

87.

A

voltage

is

now

applied

to

connection

point

of

the

starter

motor

,through

fuse

E037,

wire

1100,

relay

contacts

30-87,

wire

4002,

causing

the

starter

m

otor

to

turn.

As

soon

as

the

m

otor

turns,

the

V

IC

applies

a

voltage

to

connection

point

C44.

The

voltage

is

then

applied

to

connection

point

1

of

relay

G372

via

w

ire

4202.

This

relay

is

energised,

breaking

the

starting

circuit.

If

the

vehicle

has

a

m

anual

gearbox,

w

ire

4004

is

directly

connected

to

point

3

of

relay

G372.

CHARGING

C

IRCUIT

If

the

contact

is

activated,

there

is

voltage

on

connection

15

of

the

alternator

.

An

internal

resistor

in

the

alternator

is

energised

by

an

IC

in

the

carbon

brush

holder

.

This

resistor

ensures

that

a

low

level

of

current

passes

through

the

energised

resistor

.

This

excites

a

magnetic

field

in

the

alternator

.

After

starting,

the

voltage

on

terminals

B

+

and

15

will

rise

to

about

28.5V

.O

nce

this

voltage

is

reached,

the

IC

in

the

regulator

interrupts

the

pre

--exciter

coil

to

enable

the

voltage

to

be

controlled.

The

m

agnetic

field

w

ill

now

disappear

,s

o

that

the

generator

will

not

be

energised

for

a

short

period

of

time.

As

a

result,

the

voltage

on

outputs

B

+

and

15

will

drop. The

regulator

reactivates

w

hen

the

voltage

drops

below

27.6V

.T

his

m

eans

that

the

voltage

supplied

by

the

generator

remains

relatively

constant.

T

he

batteries

are

supplied

through

the

B

+

generator

output.

The

alternator

charging

current

warning

in

the

DIP

is

activated

through

wire

1020,

which

is

connected

to

connection

point

D29

of

the

VIC

(D900).

T

he

VIC

controls

the

D

IP

via

the

CAN

network.

T

he

voltage

on

wire

1020

is

switched

by

the

control

IC.

The

alternator

is

also

equipped

with

a

“sens”

line.

This

connection

continuously

measures

the

voltage

on

connection

point

30

of

the

starter

motor

.If

the

voltage

on

connection

point

30

drops,

it

is

immediately

corrected

by

the

control

IC.

The

alternator

will

increase

the

voltage

until

a

value

of

28.5V

is

reached

again.
